LG G5 connected to car audio unit. Not working... - LG G5 Questions & Answers

OK so I'm stumped. Got my new LG G5 and it's pretty sweet so far but I'm running into a very weird issue that's kinda hard to explain. Basically it boils down to my G5 not being able to play audio through a normal 1/8 inch headphone auxiliarie input connected to my car CD deck. Before I got this phone I was easily able to connect my old phone to my car's aux input with the same cable and worked just fine but not with the G5. I tried the same cable with other speakers and the G5 plays perfectly though anything else. Other phones play just fine through my car's aux input. Only the G5 seems to send a signal that's very faint and has a lot of static on top of it. It's very strange. I do a lot in audio production and can't explain this unless the G5 outputs some weird audio signal that's not compatible with certain aux inputs lol but that seems ridiculous...

for what it's worth
I noticed that my volume all around is much higher with the G5. My G3 was much less loud. Is it possible that the signal is too strong and the car deck is therefore producing too much distortion - have you tried just lowering the volume on the G5? I'm hardly an Audio expert, but my current settings are all practically on the first notch above 0 for most notifications whereas on the G3 they were all in the middle.

I have also noticed the volume on the G5 is quite loud. I have tried playing through the car speakers at a lower volume and unfortunately I get the same static and weak signal.

Strange thing for me is that it connects to my audio Bluetooth adapter when I am nowhere near the car. I had to plug the adapter into a lighter adapter that shut off when the car does to keep this from happening.

If I can't get this thing to work just plugged into my car system I'll have to buy a Chromecast Audio and plug that into my car decks aux input. I just don't understand why it works everywhere but my car's aux input.

i'm getting more static than music with my g5...might send it back to get another one since i doubt this is a software issue?

Do you get static on all external speakers you try? I only get static when connecting via aux input on my car stereo. All other speakers it works great!

your right, its only in my truck that i get that static noise. That is wierd af, so is this a hardware or software issue then?

So weird! I am glad someone else can attest to this happening! Really have no idea if it would be hardware or software at this point. The only thing I can think of is that the phone outputs a higher quality signal than my car stereo can handle? I have never encountered an issue like this before... I don't know what specifically could be making only car stereos not work with the G5. So weird...

Ugh. OK. Now i gotta figure out how to get to my rear aux input. lol.

That did it. Pulled out my deck and connected to the back aux port just fine. So weird. At least there is a workaround. Thanks MF Doom!

Bluetooth AD2P receiver for home-stereo

I'm looking into a bluetooth receiver to connect to my home stereo in order to be able to stream music from my touch hd. Been looking for a good page with comparisons between the different models, but with no luck. Anyone of you done any research into this? Sound quality is often overlooked in the reviews I've seen, which I find a bit weird, since it is a quite important factor for me. I mean, I realize that in going wireless you have to expect some loss of quality, but recently in a wifi-store I noticed they were streaming audio from an iphone, and the quality was really amazing. Too bad I didn't have time to find a clerk and ask what type of receiver they were using.'
Anyway, I would appreciate any kind of advice in this matter! Thanks in advance.
I guess you mean you connect a BT receiver on the stereo and streams from the HD to the stereo by BT? Ive been thinking of this myself, very interesting! The HD is a bit of a pain in the arse sometimes, when I connect my HD to my stereo I just have touch it a little bit and the phone starts playing on its speakers, the combined 3,5 Headphonejack / Headset connector is very sensitive. Is it this sensitive on other phones?
i have the sony ericsson mbr 100 bluetooth receiver and it works like a charm

Offtopic but i'll andswer anyway. My hero is fine with some headphone jacks but not others, usually the cheap cables/headphones cause the problems.
I use and app called Be Quiet for when a headphone jack does suddenly get pulled out, the media volume automatically drops to 0 (Poweramp and probably others already have this as a feature). When you plug the hedphones back in you have to remember to turn the volume back up however.
i don't know if you are still looking for it:
i use a plantronic pulsar 260. Bought it a couple of phones ago. still working. The product is discontinued by now. maybe they have a newer model.

High pitch noise when plugged into car's AUX

Full description of the problem:
I just got my EVO 4G LTE the other day, as a replacement to my original EVO 4G. However, I noticed when it was plugged into my car's AUX port, it puts out a high-pitch (like a teapot) noise. This noise happens as long as the headphone jack is powered up (something playing). Even if I turn the phone's volume down all the way, the high pitch is still heard. Otherwise, the audio from the phone can also be heard normally.
Things I've tried:
1. Different cables known to work. All act identically.
2. Headphones. They work fine.
3. Another car's AUX port. Worked fine.
4. Jiggling the jack on either end causes the pitch to change momentarily, but does not go away.
5. Slightly unplugging it from the car side (so one of the channels is not connected) makes it go away, leaving me to believe the high pitch noise is only coming from one channel (I believe the right channel, hard to tell).
Things I don't want to do:
1. Get a new car stereo.
2. Use a Bluetooth adapter. I already have the Stereoclip, and it doesn't do phone calls. Anything else sounds awful with music.
Does anyone have any solutions? I think its some sort of strange feedback/grounding issue, but I have no idea how I would fix this.
I don't have a solution, but I am experiencing the same issue with the phone plugged into my car's AUX. As long as music is playing I can't really hear the whine, but between songs it's pretty annoying.
I haven't tried playing around with the different EQ settings. By default it's been going to Beats. I may switch to a different setting or try a different player like Winamp. I'm currently using the HTC media player.

In my experience it has absolutely nothing to do with what app is being used, nor the EQ. It's nothing software as far as I can tell.

if your phone is plugged into the car charger and your audio jack is plugged in to listen to music. what our hearing is a ground loop from the cars alternator. try unplugging the power supply and see if that helps..

The car charger makes no difference. I have tried using nothing but the audio cable in the phone and still had the static.
I was under the impression that a normal ground loop would require a charger, but...
Modplan: are you sure this will fix it if the noise occurs even without the charger plugged in? The noise is high-pitch, not really a hum, so I'm wary as to whether it will help here.
Its not a simple ground loop problem. I wired my power to the phone using a separate ground from the car's common ground and the issue still persisted.
Try cranking the volume up then when you hear the noise, start playing with the touchscreen. When i did this the noise started changing according to the movement of my fingers. I concluded that there is something going on with the grounding of the capacitive display thats causing another grounding issue, but its not an issue with the car, but an issue with the phone.
I didn't want to go through the vicious cycle of returning my phone over and over until i get one that didn't have this fault so i just went with a samsung hs3000 hardwired in to my car.

I wasn't able to replicate this.
I've had the same issue, but it's only when charging. I figured it had something to do with the aluminum body and, as papadunit said, a problem with grounding and your car's alternator and blah blah blah science.

Actually had same issues this passed weekend but with my asus transformer. Was using it for navigation tethering from evo with both charging from my 400w inverter. Plugged transformer into aux and had same high pitching noise only when inverter was plugged in. Even tried different audio cables, same chit.

Headset Jack's other issues
I can confirm the same behavior with my EVO 4g LTE. My HTC Touch Pro 2 or Iphone 4s never had any of these issues with my vehicle's AUX jack. I also verified that if I turn the volume on the phone all the way down that the noise is audible on the vehicle's sound system. It also doesn't matter what player I use or if I add any equalizer settings to the audio. Finally, the noise is present whether the car is running or not.
Can you guys confirm: If you pause the audio on your player does the whine end about 4 seconds after and startup again if you press play? Or if you shut the player down does the noise go away shortly after?
I did some research and some said it has to do with the AUDIO DAC in the phone turning on and off as audio is played, paused, etc. If the output device has high sensitivity these sounds appear.
I had another issue with my Plantronics wired headset distoring when making phone calls. It did not present the whine but it distorted the callers voice as if the treble or bass was too high. I tried various audio settings but nothing changed. With other headsets the issue does not present itself. I think that the audio DAC is also sending higher/lower frequencies that are greater than some headsets can handle.
That Kensington thing that was posted can easily be made with common household parts. Basically all you need to do is take the big bulgy thing from any cable that would have it and attach it to your audio cable. It works best if you have one near each end of the cable. it's called a clamp-on ferrite bead and is just a clip with iron ferrite in the middle. Since i'm new I can't post a link buuuut what I can do is tell you the keywords to look up on google for the ehow link: cable magnets eliminate emi . enjoy!

Dankorzon, is this what you're talking about? If so I'm going to go get some tomorrow. I'm having this feedback issue too, but it is only when the car charger is plugged in. But I'd love to get rid of that sound. Drives me crazy.
SOLVED: I used a ground loop isolator
I posted earlier that I had the whining noise in my car even with the engine off. So it wasn't related to an alternator issue. I use a Blitzsafe (blitzsafe.com) device to add a line level input jack to my Honda Accord's stock radio interface. It works well with all my other devices except the Evo 4g LTE. This past weekend I did a little tinkering and noticed that if I pulled the RCA jack on one channel (left or right) every so slightly so the ground tabs weren't touching the noise disappeared. With only one channel connected the noise is not present. I'm not sure why the noise is present with both channels connected but it definitely pointed to a ground loop problem. I did some research in audio forums and some said that a wire could be jumpered so the RCA ground touches the receiver chassis and that would solve the problem. Unfortunately that did not do anything. I touched several different grounding points near the receiver but the sound was always present.
I went to Best Buy and purchased this: http://www.bestbuy.com/site/Fierce+...36.p?id=1218186610567&skuId=9855136&st=ground loop&cp=1&lp=1 It works great. For whatever reason the EVO 4g LTE's DAC must be sensitive or not have the right filter to block the ground signal. This explains why the Kensington product also works.
I also solved my headset issue. I can confirm that older corded Plantronic headsets will not work well with the EVO. The EVO distorts the speaker in the headset. I'm pretty sure it's because it sends lower bass frequencies than the speaker can handle. Only solution was to use a newer headset.
Thanks all for your help.

That is what he is talking about, but that is NOT what the kennsington device is. Google "ground loop isolator" for info on what the kennsington is, it is NOT simply an aux cord with ferrite beads on it.
I've got the same problem in my car. This only happens when plugged into the charger. I'm going to try a ground loop isolation device which will arrive sometime next week.
I guess I don't understand why the phone would only do this when no music is playing though. It makes me think maybe a patch could solve the issue if HTC knew what the issue was.

Aux Cable / Headphone Bug

So figured I'd go ahead and add a thread about this here for us Sprint users that are experiencing the problem with the Aux cable. Its a known issue and I'd link to a couple other posts, but I'm still a "noob"
I was a little upset to find that I wasn't able to use my phone to Pandora in the car.
However....
Today I got it to work, and here is how: I had the stereo set to the CD player when i plugged the AUX cable in and the icon stayed in the notification bar. Then I launched Pandora and let it start playing. THEN I switched the stereo to AUX mode, and it played fine my entire trip to work. Still experienced the "hot plug" sound between tracks, but I think I can deal with it.

I recall having an issue with my samsung headphones. They didn't work at one point, I rebooted and they were fine. The phone didn't even detect them for some reason. I've had no issues with aux in my car (aside from needing a new cable), however I thought it would be worth mentioning that my Note 2 had an issue with aux when it is on any AOSP ROMs. Selecting any app, even swiping the notification window down, sometimes even just leaving the music app and going back will stop the music from playing. The only solution for this was to go to the home screen unplug the aux start music playing and plug the cable back in and touch no other app. Again, it never did this with stock. I even went back to stock briefly because of this. AOSP seems to throw a fit with the aux cables.
I had issues with AUX today as well. Thought it was my specific phone but I'm relieved to know it's common....and perhaps a software issue.

Yeah I have it as well...I've found if I start Spotify, then plug in the AUX cord from my car, it works fine.
So I think I know the answer to this one.
It seems to have to do with how cars and some other devices treat aux inputs. For the most part it appears (at least in the case of my Prius) that with the input switched to aux the phone would not consistantly stay aux mode. What it seems like was happening is that the car doesnt actually 'activate' the aux port unless it senses a completed circuit (ie: audio playing). I have to believe this has to do with preventing feedback.
Unfortunately it seems the phone does the exact same thing. The headphone or aux symbol appears on insert of the cable because the phone senses the initial connection but then finds no load on the circuit thus assuming it is not connected and disables the port. You end up with basically an electronic stalemate. Neither one engaging cause they sense nothing from the other side. No load on the circuit.
Bear in mind this is completely dependent on the device you are connecting to your phone, as to whether it does what I'm talking about. Likewise, those experiencing popping or similar during song or track changes would basically be experiencing the same issue as during the song change the phone stops playing audio and your car kills the port. When the car kills the port, the phone kills the port, or is in the process of it when the next song starts.
To counteract this I bought an audio cable with a ground loop circuit built in. It is designed to remove the buzz from car aux audio due to the phone or other device being charged through the car's power system. But the added benefit is that it creates an artificial load on the line that the phone senses. Same idea as plugging in headphones as the earphone on the headphones creates a load on the line in the same way.
This is the audio cable I bought. Works like a charm every time, although one warning. I did experience one case of very loud static when unplugging it through the speakers in my car because of the fact that the car and the phone believe the circuit constantly is active and thus do not kill the connection to save your hearing. So be careful to only plug or unplug it when the input is not active or the car is off.

It does appear that Amazon has put the item under review for now, though I'm not sure why as mine works flawlessly, but any similar car aux noise reducing cable would work, assuming its decent quality.
An aux cable with an in-line volume control should peform similarly due to the load created by the potentiometer, although it wouldnt remove the charger buzz.

I just want my G3 to work as it should for such a simple function as the headphone jack/aux port.
I want to listen to music in my car without fannying around with different cables etc etc.
I had a Galaxy Note and S4, both played fine in the same car with the same cabling.
Shame on LG for releasing us a substandard product that cannot perform the most basic of tasks correctly.
I will say, i was extremely dissapointed when i plugged my shinny new phone into my stereo and the audio continued to come through the phone speakers. All other phones/devices work just fine in my car and there is no reason why my G3 shouldn't either.

My first feeling was confusion. I was also worried my headphones wouldn't work. But I was able to watch a beautiful high def video on my phone last night with my headphones on
Sent from my LGLS990
I just got this phone too, and although I love it, I was very sad to have this issue! I haven't had it on any other phone I have owned, so I certainly hope it is fixed in a future update. That and the video force close bug, but that is for another thread!
Guys, there is nothing wrong with the AUX port on your cars -- and they don't trigger via sound. They trigger via either conductive circuitry or via ohm load. Can you test if you are still seeing these problems when *not* charging? This issue is typically related to bad grounds. This happens to me at work when my phone is charging and I plug my headphones directly into my G3. If I pass the audio to my PC first (to the line-in,) and THEN to my headphones, the static is mostly gone.
So try unplugging the power source, and using different aux cables. Another factor is try plugging the power source into the same feed as the stereo. Sometimes this isn't that easy though.
What's happening on the back end with the sound changing between songs, etc, is that the audio codec, (the chipset,) is turning off to conserve battery. For me, when the chip turns on, it grounds the 3.5mm port just fine, and when it's off, AND I have power connected with headphones, I can get that whine -- depending on the scenario. So basically, this is by design -- an energy conservation tactic. I would be okay with them leaving the audio chip on the entire time headphones are connected.
Had this problem too and found that as long as I was charging the phone it would play like it should.
Yep, grounding issue. At work, routing the aux signal through my PC works just fine WHILE charging -- if I unplug, then I get all the machine noise.
In general, though, the headphone output is pretty crappy on this device. Even when it's "working great," there is still a faint amount of white noise that can be heard. Much higher than my HTC M7. The S5 had similar performance as the G3 though.
I just bought:
http://www.amazon.com/gp/product/B00ANDHBNS/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
And plugged it into:
http://www.amazon.com/gp/product/B00F474DVG/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
So when I get in my car, it connects to the dongle for music and the car's blue tooth for phone.
It's not perfect, but gets the job done.

http://www.amazon.com/Kensington-Reducing-SmartPhone-including-iPhone/dp/B0031U1ATQ/ref=sr_1_1?ie=UTF8&qid=1406313911&sr=8-1&keywords=kensington+noise+reducing+car+audio+aux+cable
Working pretty well. Mainly solves the connectivity issues.
Still have the pop between tracks but it's much better.
Still have the "computer talk" garbage noise related to the display coming through the left channel.
I can live with this until LG or Android comes up with a fix.
aux problem
I guess I lucked out with my phone but then again maybe not. First off I will describe my setup, I have a 05 Subaru WRX with stock 6cd changer head unit ( no aux port ) I installed a Harmon Kardon Drive + Play iPod dock. This allows me to remote control my iPod and comes with a display that shows tracks and such. It works by FM transmitter but has an optional wire which I have that connects directly between the antenna and the stereo so you get little to no loss of signal. Between the AUX and my phone I connected a PAC SNI-1/3.5 3.5-mm Ground Loop Noise device. My previous phone was an LG Optimus G which I loved, when I hooked this phone up I could listen to Pandora/TuneinRadio through my car speakers and upon making/receiving a call I would hear the call through the car speakers and when I talked the phone mic. would pick up my voice. When I attempt this with the G3 I get no popping between tracks but the phone mutes the mic and when I say mute I don't mean the mute button comes on I mean the other person can't hear me. I found if I unplug and plug the phone in during the call eventually the mic works again, but to do this while driving defeats the purpose of hands free calling. Does anyone else have this problem? (or a solution).

Yeah I have it as well...I've found if I start Spotify, then plug in the AUX cord from my car, it works fine.

Works for me, thank you.
Mines does not work at all, with headphones or aux Jack, now I have to get Bluetooth headphones and bluetooth radio for car

Do we know if LG is working on this issue? Or if it is something that can even be fixed with an update? I'm getting tired of messing with the cable just to play music in my car, and I don't want to have to buy extra accessories to get the job done.

Bumping this thread because I just started having issues. Last night I was listen to music with headphones and my device kept turning itself down. I thought it was Tasker at first but it kept happening. Today at work I wanted to listen to music on headphones again and the sound would only come through my device. I'm going to try an aux and other headphones when I get off work, but does anyone know if a system restore will fix this? I'm rooted with TWRP, I just don't want to wipe it for nothing.

They fixed it with ZV6. If you're already on ZV6 then I have no idea.

Audio qulity from headphone jack

Just wanted to know if anyone else noticed faint buzzing/scratching/hissing noises coming out of their headphone jack...
(and yes I have tested several headphones/earbuds and tested with my MDRv6's all with the same results. Its definitely the phone not the headphones)
When I insert my headphones there is a quick beeping sound that plays for a second or so then goes quiet.
When music is playing, especially soft music (a particular song was Instant Crush; Daft Punk) there is a hiss in the background, specifically when certain tones play.
It was terribly noticeable right at the beginning of a few songs, especially the one I listed above.
I also have button sound effects enabled. So When I press one of the soft UI buttons it makes a tick noise. However for about 5 seconds after the tick there is a long hiss then silence until I press another button.
The volume of the hissing/scratching noises is directly related to the actual volume of the device and the note playing.
Im on stock build 11c w/root, and I havent found a lot of info about this problem.
Just wondering if anyone has noticed this, or if this is a known issue?
If your phone is warranteed, I would bring it in
The G3 boasts an AMPLIFIED 1 watt sound speaker, which means there is a powered sound processor.. Unless the jack needs to be cleaned, I would lean toward thinking there is a defect in your phones jack, or sound assembly. I think its more than likely a defective jack, especially if there are no sounds like you are describing when headphones are not in use
Yeah the phone is brand new. I think I'm going to RMA....

Just got my G3 a week ago and didnt use headphones until I read your post, I tested many different songs with different players, stock player, google player, Iheart radio, pandora, etc, headphone sound is crystal clear on mine, I dont get any beeps either like you described, I did notice you need to make sure the jack is pushed in good and tight, I put it in and thought it was all the way in and sound was crappy, pushed a bit harder and it clicked in good and sound was great, do you have a case that may be preventing the jack from being pushed in all the way, I had a phone in the past that this happened to me with, had to cut away some rubber on the jack to make it fit snug, if none of those are the issue, I would look into a warranty claim. I am using the beats audio earbuds that came with my HTC M7 I had before this phone.

That could be the issue. I know on the 2012 Nexus 7, it's really bad. It's supposedly due to the microUSB port and the headphone jack sharing the same circuit, or some engineering thing like.
Wonder if it's the same or if they didn't shield the headphone jack very well and it's picking up interference from the microUSB port when charging?
I didn't want to leave this up in the air so I figured I would post an update.
I replaced my G3 through Verizon for a brand new unit. My first phone was of an earlier batch (came with the 10b update) the second one was of a later batch and had 11b pre-installed.
Both phones had the same issue. There is a hissing noise/distortion that comes from the headphone jack. Even when not playing music.
I noticed it on other phones too but not anywhere nearly as much. I understand that any audio source is going to have a little background interference but the G3 definitely has a more significant issue than others.
However it seems to be entirely dependant on what headphones you are using.
1st. I tested first with my Sony MDR-v6's which the problem is most noticeable on. Extreme hissing/background noise.
2nd. Then I used a pair of Audio Techina ATH-PRO500's and the problem was almost unnoticeable.
3rd. I also tried my Steel Series Siberia v2's and the problem was again almost completely gone.
4th. I also used my receiver at home. JVC 5.1 channel receiver with RCA speakers and a Kenwood sub, didn't notice the issue at all. However there where some occasional strange popping noises when no music was playing I didn't get on my GS3 or other MP3 player.
5th. Finally I tried the ear buds that came with my Galaxy S3 and the distortion was again totally noticeable with and without music playing.
This is most definitely an issue that totally depends on what headphones you are using not sure if it has to do with sensitivity or impedance (this is what most people think) however it is most definitely an issue. I saw a few threads saying that audio issues were a problem in Android 4.4.2 however LG/Verizon have yet to release a stock base on anything but.
I suppose I could flash AOSP 4.4.4 and see if the problem persists but I don't know if that would even be worth it.
2 phones and 4 headsets later this is starting to seem like either a software or a design issue.
However I have nothing but good to say about every other bit of this phone. Really besides the audio jack top notch all around.

I might have found a workaround for this
I have tested 3 LG D855 and all of them have noise/static/high-freq leak from the processor out to the headphones. It might be a faulty design for the headphones amplification stage for headphones (when the headphones logo appears on the status bar). However, when using line level output (the jack appears on the status bar) the problem does not reproduce.
Therefore the workaround I've found is to trick the phone into line level output mode and then plug the headphones. To do this you need to plug in a 3.5mm jack extensor or a 2-to-1 3.5mm Y-adapter with no load, that's it, with nothing connected to it. At that moment, the phone will activate the line level output mode. Only after that you will connect the headphones, and you'll see there are no artifacts on the audio.
That being said, I'm not sure this will work with all kind of headphones as I have only tried with mines that are low-impedance ones, but on those it works perfectly. To be checked if the level of the signal in line mode is enough to drive other headphones.
In any case, it is a shame this happens with a high-end and expensive smartphone. I was hopping this will be fixed in a newer hardware revision but I got two replacements of mine and no luck. I have read somewhere this might be a flaw in Snapdragon 801, as it integrates completely the signal routings but isolates badly highfreq noise from processor stages, etc. etc. but I do not remember where I did read it unfortunately.
I hope this helps!

Ive been having the same issue. I have a pair of Shure SE846 which are about 8ohms. I experience the poor audio, especially the noise in the left channel. I find that placing a call and then listening to music removes the left channel static but the sound is still kinda bad. Ill try your suggestion tonight and post back. Just wanted to let you know your not alone.
I despise my G3 because of this. Im looking to get a new phone unless I can fix this.
Nope, my sound is perfect on my high-end Sony over the ear phones. Crystal clear on pure stock G3 .
I haven't noticed any artifact issues on my phone when using headphones, however when I plug it into my vehicle and also plug in the charger that causes everything to go nuts. The USB interference causes a crazy amount of excess noise. I haven't ever actually tried listening to headphones while charging, so in the car is the only time I've ever noticed it. The same issue occurs when I plug in my Galaxy Tab Pro into the aux jack and charge it at the same time, so this is definitely not unique to the G3. I wish all phones had as good an amplifier as my HTC DNA does, I still use that thing for music because the sound is so good.

I'm having a different audio problem.
With headphones plugged in and listening to music using any player, the right side sound emits distortion/hissing noise at a certain frequencies. When I tested it with plugging a 3.5mm to 3.5mm to an external amp (JDS labs c5) the distortion/hissing noise is completely gone. So it's definitely not a faulty jack
The hissing is evident at the beginning of (first few seconds) Tina Area's Still Running and You set fire to my heart .
I'm testing it with sensitive iem (Westone Um3x).
So does this mean there is a problem with the internal amp of the g3 or more to do with the os bug that can be solved with a custom kernel or update.
Is this a common issue found on all g3s?

Hi! This worked perfectly for me but for me instead of tricking the phone into line level output mode, I detaching one side of my headphones before plugging it into the headphone jack then reattached it afterwards. I'm using pair of sensitive iems (Westone um3x rc)
Everything is quit with no distortion, just how it should be!
One thing, is there an option within android or an app that can permanently enable line level mode ever time headphones are plugged in without having to trick it.
If so, I won't have to sent my phone for repair!
Also are there any disadvantages for using line level with headphones?

Using line out shouldn't make any difference on audio quality. It only disables the remote (buttons and microphone).
Would also really like a way to force the line-out mode. Btw, does this affect all G3s? Cause right now I'm not sure if it's worth the hassle of replacing it.

I know but some how using line out causes the hissing from the right side to go away completely. Strange huh
Are you also having this problem?
I also don't want to return mine if it exists in all g3s and there's a easier work around.
Yea same thing. I have artifacts in the left channel except when I manage to force the phone to recognize the headphones as line-out. I did this with the adapter to test it and it's impractical if not impossible to use the same adapter all the time.
I'm gonna try doing this right this moment to see if it works: http://forum.xda-developers.com/lg-g3/help/hissing-noise-left-ear-playing-music-t2804065/page17

I don't use earphones with a volume remote or microphone so that's not a problem.
It could be more to do with the increase in output impedance but I might be wrong cos the volume level is identical to headphone out.
I'm also getting a lot of static background noise but it disappears after making and hanging up a call as mentioned in a thread.
But yeah a permanent fix by forcing it into line out or doing some changes in kernel would be much more convenient

I use an aux cable in my car to listen to music and podcasts.
when starting spotify i experienced incredible amounts of static, no matter what volume both the phone and car volume were set at.
Anybody else experience this?

Might be the worst static and fuzz ive ever experienced through a phone. Dont know what to do.
Any updates on this?
Mine comes out with an incredibly small amount of movement. Anyone else have this issue?
Nvm I just was being too easy on it. Requires a lot of pressure relative to anything else I've had for it to lock in.
Also you guys should dip a q-tip in rubbing alcohol and clean out your cars and phones headphone jacks. Especially in a work truck I imagine there's significant dust build up in there.
....cable
I found this too, even the headphones supplied need a fair amount of force to connect - at least they won't be pulled out so easy!
1 Maybe RF from cell communication leaking into audio or power cable.
2 Try with phone Not plugged into car power (I assume you run this with charger cable connected).
3 Try with better quality aux cable, maybe one that is shielded.
No fix. so aggravating.
Mine are flawless.
I just got the g5. Same issue. Tried multiple cables. Headphones work fine but not the aux cable
Just got my G5 a few days ago and I noticed this too.
In the car using a downloaded playlist on spotify and got terrible static noises (haven't tried any local music files as I don't use any!)
Sent from my LG-H850 using Tapatalk
I tried it in another head unit and it works.
Aux cable works in my Alpine but not in the Kenwood.
Ok guys and gals. I've been dealing with this for a bit and I found a fix of sorts. First off, two G5s (a buddies and mine) both had static in my car, but no static in his car or my mother's car. The difference being is that I have an aftermarket JVC player (removable face plate, auxiliary jack in front). The other two cars had factory stereos. I was guessing it was an aftermarket thing. Weird, I know, but that was the only commonality. Even more odd was that out of four phones the G5 was the only one having the hissy fit.
On Reddit some people were fixing this problem with a "ground loop isolator". It's basically this little noise filter device that plugs in the audio jack. Maybe $15 on Amazon. Anyways, I was about to order one, but before that I decided to take the head unit out of my car to see if any wires were loose. No wires were loose, but what I did find was an alternative 3.5mm jack in the back of my stereo. I'm sure not all stereos have a second port, but there's a decent chance. My particular head unit isn't what you'd call fancy by any means and it has one. So I plugged it in the back 3.5mm port and wouldn't you know, crystal clear sound!! I was so happy when it worked! Now instead of putting my stereo to "auxiliary" for the front port. I have to put it on "bt audio" to access the rear one. (whatever bt audio means, who knows, but it works).
So that's basically it, find out if your car stereo has a secondary 3.5mm port in the back and give it a shot. I didn't realize it at first, but right next to the front auxiliary port it actually says dual auxiliary/audio port. It could be an easy way to find out. As for rerouting the cord. I have a little pocket directly under my radio. There was a tiny hole in the back of the pocket/tray that I put the wire through. It looks cleaner than having it stick out from the faceplate of the radio any way.
If your stereo doesn't have a second 3.5mm port in the back You may want to check out a "ground loop isolator" from Amazon.
Good luck folks. Peace.
Not sure if could post links to the isolator. I'll give it a try.
Kresk - Here is the part that will boggle your mind with this issue. Go and play the stock LG sound file on the phone (The "High Quality" audio track). Once that plays, the static stops. Then switch to your regular music app - I use Spotify - and the music plays static free until the built in music app closes in the background. Then all the static comes back. If there was some way to force the phone to stay in whatever mode it uses for the High Quality audio track, it could be a great fix.
I've also found that there are three different "modes" of static I get on my phone too
1) Static Free
2) Low level of background static, volume independent (volume stays the same low background noise)
3) High level of static, volume dependent (Higher the volume, more static)
Typically when I do the thing where I get it into High Quality audio mode or whatever its using, I get 2 when immediately switching to Spotify. If I lock and unlock my screen, it goes to 3.
I'm going to go and try to plug into the "BT Audio" port on the back of my JVC head unit and see if it works. Will report back on it. I also have a ground loop isolator coming in the mail tomorrow, so I can give an update on that as well.
~PubstarHero
You might need a Ground Loop Noise Isolator, such as this: https://www.amazon.com/Mpow-Ground-Isolator-System-Stereo/dp/B019393MV2
I am thinking of getting one for an issue similar, but not the same as yours.
Same issues, in general. Static on most aux cables, and in my case some headphones don't work at all. My higher-end earbuds work flawlessly though, so go figure. Not sure what to do about it other than the ground fault isolator, though I was about to start looking into a Bluetooth-to-aux module.
