I'm having a problem hearing music using ear Buds / headphones and was wondering if anyone else was having this issue on titan. The sound goes real dull almost like non-stereo and I have to hold where the 3.5 mm jack is and wiggle the earbuds to get a clear sound. I bought new skoal candies and tried 3 other pairs so I'm guessing its my phone but was curious if anyone else was having this issue.
Thx
from Titan on XDA Windows Phone 7 App
ear buds and the like
It might just be your 3.5 mm connection...I tried mine out just now (I had not added music to my Titan previously) and plugged in and was very very pleasantly surprised at the sound quality. I had surmised for myself that my PDA was for phone and calendar etc, and the iPod or other MP3/4 player for audio - mostly for quality of sound. I won't make that mistake again. The Titan is good - very good.

DId you use IE while listening to Music? I don't have any problems with Music playback (Used it to listen to my music collection during work hours whole last week) However I noticed that when I launch IE (search, or by launching IE on its own) sound quality suddenly changes, and degrades..

Hm, I think it has something to do with bluetooth stereo vs headset profile. Weird that it happens with regular ear buds.

I think its defective, I'm going to call ATT tomorrow and have it replaced because I have to hold where the earbuds fit into the 3.5 connecter and put a little bit of pressure to get the sound to come thru. I'm glad to hear no one else is having an issue so thats good
I'm having issues too.
I had problems with my audio jack too. I was looking on here to see if anyone else had issues. At first, I thought that I had a failing headset but then I put another one in and after awhile it started doing the same thing. It's not right away but it seems to start up after a bit. It's really concerning me though. I'm considering getting a replacement and hope this is just a minor issue that affects a few units. I don't want to wait and have it develop into a bigger issue. It frustrates me though, because I had originally bought a focus s and the hands free button didn't work right. It seemed like an issue with the way it registered button presses. Now, I get this phone and the button works right but I'm having these audio issues. Argghh.
I don't have a problem with any earbuds , every one i tried works for me. It might just be your phone itself. maybe deffective? If i was you i would try regular ipod headphones or a friends to see if that really is the problem
hi all, question about the volume sensitivity on the titan. i used to have an iphone 3gs then switched to the skyrocket to try out android but i'm really unhappy with the android music players so i'm either going to trade it in for the iphone 4s or the htc titan (still within the 30 day period).
on my iphone i could set the max volume to wherever i wanted and would have plenty of intermediate volumes to get the level right where i want it.
however, with the skyrocket by the time i hit the 3rd volume level (0=mute, 1= up volume button pressed once) the volume physically hurts my ears and i like loud music.
i'm using the stock headphones that came with my iphone 3gs because i like the fit and the in-line remote. i know these have low resistance but still, only having 2 usable volume settings is ridiculously annoying because i can only listen to music really softly or a bit louder than where i want it to be.
how do you guys feel the volume sensitivity is on the titan? are there more than 2-3 acceptable volume levels for low-resistance (small earbud) headphones? thanks!
i use the included earbuds and the 30 level volume settings seem to fit most situations
Replace it since you're within the 30 days. I got a new one and the issue is cleared up, I had a defective unit. Very happy with it now
I haven't seen this posted about the Note. Does anyone else have a bad hiss when listening to music? Using Google Music and spotify, there is a definite hiss in the background.
I realize the Note's audio chip isn't great but I wasn't expecting this. Coming from the Captivate, this is really annoying me at the moment.
I hear it only in headphones
I don't hear it on the speaker or via BT. Haven't used the headphone jack yet.
Right, only on headphones. Quite loud and intrusive. I listen to my good quality in-ears at work for hours every day. I can't believe just how crappy the sound is on this otherwise fantastic device.
Ok, you got me wondering so I put on a decent pair of over-the-ear cans and spent 10 minutes flipping through a half-dozen channels of XM (128 kbps streaming). Then 5 more minutes going through several high-quality MP3s (variable bitrate with a max of 224 kbps).
No hiss, no background noise at all during the soft parts. Cranked the volume up to max, no distortion. Very happy with the results - much better than my last phone, the onboard sound on that sucked.
I'm on the stock rom, are you using something else?
For mere there's some noise when I'm not listening to anything, but I only hear it on my headphones.
In car Hiss
have not noticed it with headphones...but.....While using the car dock, any pause in the music whether it be on Pandora, Google Music, or just no app selected, There is a really annoying hiss/feedback through the speakers in the car. This is using the audio output connected to my stereo's AUX input.
It's just like a bad ground "whine" on a stereo...speeds up and down with the car. Never did this before with any other phone/device, so I know it's the note or the dock. I have not tried connected directly to the headphone jack on the note, I'll have to try that out.
Yeah the skyrocket did that too. I have a video up on you tube of it.

As stock as can be here. The hiss is most apparent at the beginning of the track when it starts playing but no music yet. As soon as the track starts playing, you can here it click on with the hiss.
Did I get a defective one?
I'm using a very good pair of in-ears (UE700s). I'll try to dig up some cans later to try it. Maybe directing sound directly onto the ear drums via in-ears picks up the hiss better (less natural filtering?).
Another thought: is there an internal amp volume/gain? Listening to the in-ears, it seems the media volume is very loud even at low settings and amps up quickly with each keypress. Maybe there is another sound tweak I can make somewhere.

A common problem if you are also charging - you are setting up a ground loop. You can add a ground loop isolator on the audio cable (big and clunky), unplug the power, or unplug the audio (and use BT in its place).

While I'm not a die-hard audiophile (I won't spend 10K on a sound system) I do consider myself to be pretty selective. Partly why I ripped my CD collection @ 224 and not something lower - I did lots of tests beforehand and still could hear subtle differences @ 192. Also why I rarely buy 128 kbps mp3s. Anyway, for better or for worse I just don't hear anything negative so maybe yours is defective. I will bust out some in-ear buds tonight and take another listen.

Often media players will have a separate volume from the phone's "media volume". Then there are separate "media volume" settings for BT and the jack. Then don't forget internal volume on BT headphones. It can take some fiddling to find the best combination.

I had the same thing with all my devices. Its just bad ground. That cable will get you set straight.
I never listened to my note with headphones, just with my car stereo with that cable. I hear absolutely no hissing or whining noise, just absolute beautiful sound and bass. This phone is mounds better than the Captivate.
Well, I retried some EQ/volume apps that I might has used recently to make sure there isn't any overboost feature enabled but nothing I can do to solve my problem. argh...
I never tried headphones in my Note with the stock sound equalizer. I had already installed the Beats by Dre mod in the developer's forum.
Zero hum whatsoever, and my happy hardcore sounds amazing.
I too have hiss from the headphone jack. I just returned my first Note yesterday hoping that the hiss would go away. It did not. I use mine in the car with an adapter that hooks directly to the back of my radio (JVC proprietary style).

Huh... I was about to return mine today but maybe it might be fruitless? Or maybe there is a large quantity with hiss and others without?
For those with no hiss, do you find the volume to be very loud? What I'm talking about is even at low settings, just 2-3 notches above silent, the volume is already pretty loud. My phone feels like the internal "gain" was set too high.
I know on my captivate, I could set the media volume to about 40% and still be comfortable. On my Note, it's about 20-30% if that.
Does volume of the note sounds real low to you compared to smaller phones???

No, it is TOO LOUD. just a couple notches above zero and some music is already getting too loud. This is with headphones not internal speaker.
I just got back from swapping my phone from the AT&T store. Both models (black/white) on display had the hiss. I decided to go ahead and swap and maybe a new shipment had an updated phone. NOPE, the hiss is still there.
I've used 3 different in-ears (couldn't find any over the ear cans) and also tested on a captivate and galaxy tab 10.1. It's the Note that is doing the hissing and very noticeable even at low volumes. Easiest to hear is right when you track begins but before the music starts.
I think this might be a deal breaker for me. I love this thing though. Especially irritating with spotify between tracks.
music end -> hiss -> soundless gap -> hiss 0> music starts
Anyone know of an app (probably one that requires root) that can adjust the internal gain like what voodoo sound did?
This older thread I just found (post #5) seems to describe my problem as well.

In order to quantify if this is hardware or not, try doing a factory reset (since you've returned your phone it shouldnt be that big of a deal).
Then, using the stock player on the phone (feel free to update Google Music or any other apps that came with the phone) see if you have the same hiss.
The factory reset is to determine if its possibly an app you installed at some point that is 'boosting' the sound internally without your knowledge. Sound boosting can create signal to noise problems.
Make sure your phone isnt plugged in / charging to anything (not plugged into a PC for example).
And try moving around to different locations, for example, in your house, try going into your front / back yard and see if the problem persists.
You also might try a different set of headphones and see if you have the same issue.
And lastly, if you plug in the headphones and reboot the phone, once the phone is fully booted, check to see if you hear any hiss WITHOUT any apps open?
As a side note, I just tested this (believe it or not, Ive had the Note for 3 weeks now and never plugged in headphones) using Seinnheiser studio HD 600 headphones (very expensive at around $600 for a pair and VERY power efficient) and have no hiss. However, the sound quality isnt all that great but that is a different issue.

Thanks for your helpful tips. Unfortunately, I've tried all that. Factory reset and all. As soon as the phone is ready to go, I listen to some music and hear the hiss immediately. Home or office, no difference. Not plugged in. Different in-ears. 4 different Notes.
I'm using very good in-ears (UE 700s, dual armature) and also decent SuperFi.3s.
Something interesting. Took a listen to a friend's good headphones just now and do not hear any hiss. Even if the media volume cranked up close the max, sounded fine, no hiss and listenably loud. With the in-ears, I can barely get half way up in volume because it becomes too loud.
Anyone here use in-ears? I know most prefer headphones or earbuds.
I'm going to try an inline attenuator tonight to see if that helps (if I can find it!).
What do you mean 'as soon as the phone is ready to go'?
As in, the instant you plug in headphones the hiss is there?
My guess is likely that the in-ear headphones are putting the sound right up to your ear drum and they likely are super sensitive.
The sound chip in the Note is not near to as good as the sound chip in the Captivate.
Im going to do a bit more experimenting with this as the only headphone I have are the seinnheisers and they arent exactly great for portable listening. I have a friend coming over tonight who has some very high quality in-ear headphones and Ill see if I hear anything with those.
I have heard many reports atleast on i9000 (Galaxy S), that Spirit FM has broke external- and internal speakers.
Is this issue only on i9000, or on i9100 too?
Have used it mostly with headphones.. No problems so far.
I would say proceed with caution. I've installed Spirit FM for the first time. I've always been reluctant after reports of it killing speakers, 21 Galaxy S' according to the developer. What I will say is this, it's a well-known fact that volume alone doesn't kill speakers, the frequency is just as important and therefore the audio/signal generated (whether it be music, talking, noise) is a key factor. That is why a cheap set of OEM car speakers (usually made to run at anywhere from 15-30 watts) can often handle a high quality head unit that outputs 40 watts, little noise, with good equalization and most normal users are smart enough to leave off the heavy bass. In truth, volume is an important factor, but not the definitive one.
I installed Spirit today, and immediately plugged in my headphones. I don't use my FM Radio on Speaker Mode. The first thing I noticed tuning in to the first station was that it was incredibly bassy. Remember what I said about frequencies? Low volume unfiltered bass can do just as much damage to a speaker as something normal played at ultra high volume. It may have been my earphones (cheap pair), it may have been Spirit. I don't know, but it convinced me that I don't want to even try it off headphone mode.
I will take a risk later, I will drop the volume and pull the earphones out to see if it automatically reverts to speaker mode. If it does, it's uninstalled straight away. I can't take the risk of blowing my speaker. If it dies and says insert antenna, I will happily go on using this software although I don't like the idea of being able to press Speaker at the bottom by accident. I'll have to immediately minimize it when using it in the future.
OK, i pulled the cable out. It doesn't switch to the speaker automatically. This is good.
In my opinion, the app is worth keeping but be careful with it. I don't exactly know under what conditions the Speaker blows occur, but they do happen, so I'd suggest only using headphone mode only.
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?

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!

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

Great news! I just tried the fix from that thread and it worked. Here's the post: http://forum.xda-developers.com/showpost.php?p=59601465&postcount=150
I'm using stock rom which had 3 mixer xml files and I edited 2 of them, mixer_paths.xml and mixer_paths_qcwcn.xml. Also, instead of changing the value to 0, I deleted the entire line as it was suggested later in the thread.
The artifacts/noise in the left channel are gone!

But mine is stock on stock Lollipop via official update and with the hiss coming from the right side.
Please excuses my ignorance but I know nothing about accessing and editing a ROM.
How do I get into the rom and into the file called system/etc"?
Hi,
I'm wrestling with my new S9+ (after upgrading from my previous S7 Edge). The new stereo speakers (or maybe its Atmos?) are extremely loud. Never in my life have I watched YouTube videos on less than full volume... till now.
But when using Waze for turn-by-turn navigation I can barely hear the instructions. My S7 edge was much louder! I do drive a very loud truck, but the truck is the same, the phone cradle is the same. What has changed is the phone and the OS.
Is Waze lacking some sort of special access permissions to the stereo speakers or something like that? I have all the phones volume controls to the max, I have the Waze app volume to the max, I have it set to play over phone speaker.
What am I missing here? It seems to me that some apps have access to more volume than others...
Thanks,
Matt
