I just got my S4 this week. I recently changed phones from the Note 2.
When I play music via the 3.5mm cable to my car's Aux input I hear static only when no sound is playing. Also, the quality of the music isn't as good as the Note 2. I would suspect that the clarity, range and overall quality of the S4 would at least be at par to my Note 2.
Just this morning I unplugged the usb charger and the static stopped. I have not been able to replicate this issue with headphones or other chargers. Normally, I would suspect that one of the cables are going bad. However, the same cables work fine with the Note 2.
There appears to be the metal of the charger is hitting the metal bezel/border around the phone that the 3.5mm input is resting on causing (grounding?) the static. Has anyone else experienced this? Is it a known issue? I want to make sure it's not a defect on the phone.
If anybody have any solutions or recommendations on better cables please let me know.
Thanks

The metal-looking bezel around the phone is just painted plastic. I can't say I've experienced this issue, and it's strange that it doesn't happen with other headphones.

I used a different charger when I tested the headphones. I'm going to try headphones with the same charger tonight. Is it possible there's an internal short or ground causing this? I read other people having static over the audio but I only hear the static when no music is playing that includes changing songs.
There is a known issue with SOME GS4's and their headphone jacks causing static or crackling noise during playback. It is a random issue and seems to be an issue with certain types of headphones or whatever is plugged into the jack. For example, you can use the headphones the phone came with and they are fine but some aftermarket headphones have the issue. This is 1 reason why i didn't preorder my phone online but went into a corporate store and had them test it before they set it up.
My advice, is since you're inside your 14 day return policy i would return for a new unit.

Could be a grounding issue between the audio in car and your charger. May need to isolate the ground....

Same issue here
I'm having the same issue with static/buzz between tracks with the charger plugged in. I believe there is a grounding issue in the phone itself. I've had several other devices plugged into the same cable with no issues. It's really annoying. What's odd is that there's zero buzz when a track is playing. It only happens when the tracks change.
Update: I just checked it with a coworker's S4 and the same issue is happening. Also, if an audio application is not running the buzz is heard when the charger is plugged in. As soon as an audio application runs the buzz goes away until the songs/tracks change and then it's only making noise between the tracks. Seems like something in the audio section disconnects when there's no audio. Definitely a Samsung issue.
Im also having the exactvsame issue that Icecreaman is describing to the T. So my big question of the evening, is it all VZW S4s or are there a bad batch? Because if its a bad batch I can return my still for a new one...
Thoughts.

Ok so it gets more interesting. I grabbed my wifes S4 which I got from a differnt store 3 weeks apart from my as well as the fact that mine is the white variant hers is black.
Now what I have realized at least in my vehicle is that it only does it for her phone when I have the aux cable plugged in AND micro USB is plugged in and charging. If I remove the micro USB the cutting/popping is none existant. I will try it with mine tomorrow. I suggest you guys try the same thing and post results.

I do have the exact same results with both phones tested when micro USB and Aux Cable plugged in. Sorry for not making that more clear in my last post.
99% sure this is a grounding issue in your car, and not a problem with the phone. My old Droid Bionic, Droid RAZR, and now my Galaxy S4 all do the same. It's a grounding issue, not the phone. Do I know how to fix it? Unfortunately no.

Definitely not a grounding issue with car. Once an audio app turns on there is no noise, even when music is paused it's dead silent. I also was able to reproduce the issue with a set of computer speakers in the house to eliminate the possibility of the car causing the issue. It is a ground problem but it's in the phone. Samsung is disconnecting something in the headphone section of the phone when there's no audio apps running. If I plug in my micro USB and AUX jack in the car with all audio apps closed I get a constant buzz. It sounds similar to the sound you get when you touch an audio cable that's plugged into an amp. I've tested three phones now all with the same problem in different cars.

Wow, so I'm definitely am not alone. It's exactly as everyone describes it. I also tried using the same micro usb charger and a headset instead of my aux cable and no issue. However, I just bought this off Amazon which eliminated the issue with my current phone. :
Kensington Noise Reducing Car Audio AUX Cable for MP3 or SmartPhone, including iPhone 4S (I can't post links but that's the title on Amazon)
I'm also Verizon also sent me a new phone to exchange my current but it sounds like the new phone will still have the same issue with my old cable. I'm debating on whether to just send the new one back or not since i just burned one of my three screen protectors.
But I can defintely confirm that if it's not a defect and an actual flaw in the phone then those headsets eliminates the issue.

Seems like its a wider-spread issue and no you aren't alone. I also have an issue with the volume dramatically increasing and decreasing while plugged into my AUX in my Tahoe. I was poking around the other S4 forums for the ATT, TMo and Sprint variants and its apparent there too. However the consensus is that issue is related to The Google Play Music app and more specifically the EQ.
I have had 'noise' on my AUX line in my truck before and it would be expected without a ground isolator however it seems worse with my S4.
So it seems that common wisdom here would say that a new replacement phone would not do any good?
-Lil'
I had the same issue in my truck with the s3. I think it was a ground issue.
There was improvement with the replacement device bu5 the issue wad still present. But the Kensington wire does eliminate the noise so it's definitely worth checking out.

I plugged my headphones in for the first time today and i realized that the left side was quieter than the right. And I unplugged it and replugged it in and it was fine. Then I tried it again and the left side was lower again. I'm not sure what's causing this or if my tablet is defective. But it seems like a hit or miss on getting even volume from both sides.
Anyone else having this problem or can test it out?
I have te same issue and it happens every time I plug in headphones and its annoying.
For me this only happened when I use my SGS2 headphones on Nook.
Actually, I found that SGS2 headphones only work well on the SGS2. With my laptop they have tons of noise, on nook sometimes I have uneven volume.
Although on SGS2 they have the best sound I've ever heard in headphones..
Have you guys tried other headphones?
I only have the one pair of head phones and they are a generic brand from dollar general and they dont have any issues when i use them with either my pc or psp or phone for that matter

Headphone bug
Yes I too have that problem. Glad to see that it's not just me & mine.
Stupid question - for those having issues, have you tried wiggling or rotating the plug once it is plugged in? Sometimes I find if I have a spot of oxidization on the plug it will cause said uneven volume. It could explain the difference that occurs when you unplug/plug back in.
Another thing to try would be to plug them in when the device is asleep to see if that helps. If there is anything that tries to reduce the "pop" of the sound of plugging in the headphones it *might* affect how they sound after the fact.
Just grasping at straws here based on my experience with other devices.
I was having this problem until I realized I only had my headphones plugged in half way. Don't mean to be a jerk, but have you tried plugging your headphones in just a little further?
Sent from my DROID BIONIC using Tapatalk
no amount of fiddling with the plug helped me at all still have the issue and its annoying since the speaker isnt loud enough when I am out and about.
Another thing to consider - another issue I've had with certain device/headphone combos is that some headphone jacks either don't have a long enough plug or the plastic jacket of the jack interferes just enough with the plug in the device to affect sound (essentially related to downsay's comment). Try a cheap pair of 'phones from the dollar store with a simple jack and see if the problem persists. If so, perhaps the device is defective...
These are a cheap pair of head phones from dollar general lol.
Edit: Plugging the headphones in while the device was asleep seems to have fixed the issue for me for now. Sound is equal in both cans now
I have tried 4 different earphones, they have been plugged in all the way. Some people have no problem, so I'm beginning to think this is a hardware defect. I'm going to exchange mine and will let you guys know if there is a difference. I'll also try out the display model and see if it suffers from this problem.
Glad to hear you got them to work. Please do let us know how it goes with returning the nook tablet.
Sent from my DROID BIONIC using Tapatalk
I replaced my Nook twice partially due to this issue. Same problem on all three and it's always the left channel that is not connecting properly. I have found that I can get a good connection by plugging the jack in slowly. I think this is more a software issue than a hardware issue.
Yea just exchanged my tablet as well and the same issue is there as well as the one at the store. Plugging in slowly does help. Just before it engages the last click, if you hear both channels you're golden. Hopefully this is a software issue because it seems to be random. Unfortunately the one I exchanged has a creaking case, so now back to exchange again.
I stopped by Radio Shack this afternoon and purchased a $5 female to male 1/4" stereo connector. It seems to have solved the problem. I had similar problem years back with an iPaq PocketPC. Due to the shape of the hole on the iPaq/Nook, the headphone/earphone connector isn't inserting deeply enough.
Another solution would be to use something like a Dremel Mototool and shave away some of the excess material on the headphone/earphone adapter, so it can insert a little bit deeper.

What is everyone testing their audio on? The stock media player? Video (what program)? Is it on every application you try?
I haven't had any issues with audio in games, websites or MX player at all other than a loudish pop when some programs start up, but I'm using a set of Denon stereo headphones (so, good (large/long, gold) headphone plugs on it, jiggling the connection does nothing).
Hello everybody i recently got the sprint car dock and i was wondering if anyone else has seen this same kind of behavior as I have been seeing. Basically music played using the 3.35mm jack to an aux port on the car stereo just doesn't sound right. It seems like all the sound is going to my rear speakers while i play music from RDIO and my streamed music from Google play. It seems like the audio sounds much better while the phone is not docked. Has anyone else run into this issue? I remember that original Evo's dock did something where it automatically lowered the volume of the music being sent through the 3.35 jack.
When I had the photon and the dock, I had the same issue. Do you have a case on your phone?
If you do try to push down a bit harder with music playing, I bet you your other speakers will start working again.
The USB audio is picky on just how "properly" seated it is. I also noticed (again the photon) the audio is a bit quieter. Eventually I ended up using the mini jack connector and the usb for charging.
So after re-reading your post, I realized you are not talking about USB but the mini jack. What i have noticed however, I was using the 3.55mm today and the radio had to be turned up a bit more to get the normal listening levels I am currently used to (used to be 22-24, now its 30-35 for volume level on my radio) The sound did sound a bit.... off... but could not quite place it. I noticed the beats audio icon on the top when I had the music playing. It does not appear to be customizable except for an on and off?
anoying sound
As soon as I inserted my phone into the car dock with my 3.5 audio jack in it started making a buzzing sound. I double checked that the phone was seated properly and that the audio jacks were all the way secure. The sound disappeared as soon as I removed it from the dock. It is not very noticible if music is playing but if is not it is terrible. Am I the only one?
This is likely a ground loop issue. I'm seeing it with my dock too. But i also see the exact same issue while charging WITHOUT the dock and always have with every phone in my truck. Unplug the charger, issue goes away.
Eventually I'm going to re-ground my cigarette outlet to a cleaner ground in my truck and see if that solves the issue.

Id have to agree. I dont have the sound issue in my truck atm, using an aftermarket Pyle 7in dvd. But Ive had that same issue in other vehicles/devices (not with my LTE). Does the sound increase with the RPM at any range? If so they make a filter (I think its just a magnet idk) that can clear up that sound.

I do not have the issue at all when I disconnect from the dock. In fact, its minimal once I start to play something like Pandora. But as soon as I don't have something playing the buzzing kicks in and its annoying as hell. I have two 12v ports in my car and several different chargers and it does them for all of them. I think it may be something HTC knows about but hasn't confirmed yet...

I'm not saying that it wasn't the case for you, because it certainly is possible. However, correct me if I am wrong, you had the problem regardless of if the phone was in the car dock correct?
I ONLY have the problem when it is in the car dock. That makes me think it's not the 12v plug.

Can you try something? Take the same charger and try it with the phone in another car. One thats less then 10 years old if possible. (Not that its some magic age of the car, just better/properly grounded radios are more common, imo) Report back and let us know if the sound persists in that vehicle? Thanks
*Not saying yours, or anyone with the problems vehicle is 10+ years old - just wondering if it persists elsewhere.

I've had it on multiple devices that had their power adapter plugged into the car. There is also a chance it's your power adapter.
This is not an uncommon problem in car audio, it's so common that many manufacturers make devices to try to reduce the noise. http://www.radioshack.com/product/index.jsp?productId=2062214
Try adding a ground loop isolator into the audio cable. They can't be bought just about anywhere (Amazon, Radio Shack, etc.) for about $15 and should eliminate and ground loop noise. Ground loop noise is why it is so hard to find a car dock that includes audio out. Companies understand consumers want a car dock with 3.5mm audio out but wouldn't be able to design a dock that would eliminate noise in every case.
Filtering the audio line with a ground loop isolator is not a solution for me. They often dramatically reduce high tones and degrade audio quality overall. A real solution is to solve the issue on the electrical side, not the audio side.
OK, I think I understand what you are saying now. I get the normal ground loop whine that I have always gotten in my truck, that changes pitch with RPMs. Known issue with all phones in my truck, whatever.
But today I also noticed a Static (1 second) Static (1 second) Static (1 second) Static (1 second) that was only noticable when my phone was in the dock, plugged in, no music playing (in between songs) AND the beats audio logo was visible (beats was off, I do not use it). Beats logo goes away (when there is more than a second or two of silence) and the static stops. I'm not sure if the static is stopping then because the beats signal processor is turning off, or because the phone is turning off power to the headphone jack. If it is the beats processor turning off, I could try to make a mod to always keep it off (I don't use it anyway).
Is anyone seeing this static (static, not whine) while plugged in but NOT in the dock?
Is this what the OP is seeing? How about the rest of you?

I am not the OP but I am getting the exact same results that you are. It sounds perfect when not in the dock. When in the dock it makes a terrible buzzing noise until I start to play something. I have tried multiple chargers including OEM HTC ones in multiple vehicles and the problem still persists. How can ground loop be non existent when I'm charging my phone with just the cable (outside of the dock)? It has to be something else. I ordered the HTC Stereoclip yesterday and should have it be the end of this week to test wireless play.

Just out of interest, is the 3.5mm jack going into the Phone, or is it tied into the charger cable. I currently have a MOTO Atrix and the Car Dock USB Cable splits off with an Aux Jack connection. That way you don't need to keep plugging the Aux Cable into the phone everytime you dock. I've never had any interference with this approach.
I'm getting the EVOLTE as soon as possible, so I'm interested in this answer. Plus, how it's being connected may be part of the problem?

There is no audio jack coming out of the dock. You still have to use the one on the phone itself.
So I took apart the dock and there is one small chip inside. Seems like a lot for what should just be usb passthrough. I tried removing the blue led hoping that that was the cause of the interference but it did not help.
There are lots of resistors and capacitors on this board. Does anyone know of we remove them all it will be straight usb passthrough? I get MUCH less interference in my truck with just charging and NOT the dock using the same cable. I good way to test this is to turn the Media volume all the way down on your phone and up high in ur vehicle and you will get tons of static and popping.
Any electrical engineers in the crowd? I if not I guess I have to buy a stereo clip :-(

Activating car mode is done my simply shorting pins 4 and 5 on the USB connector, no electronics required and is why the dock will still put your phone into car mode when not even plugged in.
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.

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.

I'm happy to report that this actually did solve the problem, amazingly. Thanks!
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!

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.

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 am getting this with headphones, i have used multiple brands and its hit or miss but more hit than miss :laugh:, anyone getting it in there headphone?
I was getting this issue until I installed a custom ROM. Running MeanROM right now with no background noise. Seems counterintuitive to me...but whatever.

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.
I've got an aux input in my car, and today when I tried plugging in my GSIII, I got met with a faint but annoying whistling sound underneath my music.
It stops if there's no sound being sent over the wire, but the moment a notification (or music) starts playing, it comes up.
Car worked fine with my DX, and still works fine with my friends' iPhones, but I get the stupid sound with my brand new galaxy siii. Oddly enough, it works fine with headphones.
any ideas guys? I'm kinda stumped.
Search ground loop isolation. You are getting dirty power to your phone.

Do you have the phone charging through the cigarette lighter? You can get ground noise from there, and it will be transmitted through the phone to your stereo.
Hm. Let me try again without it charging, but that's strange. Why did my old DX not experience this?
Assuming that's the issue - will a different cable solve the problem?
edit: So I checked the phone without plugging it into the charger. Still get a whistling noise. It's really more like a high pitched hum. I notice that if I don't plug the plug in all the way it doesn't happen (but I think I only get one channel).
I'm getting the same thing, and it's driving me crazy. At first I thought my brakes were going bad in my car!
I've tried different audio players and apps, but it still always get the noise. The phone is not charging, and I did not get this with my old captivate either.
Any ideas?
Doesnt happen in my Porsche. I'm using Bluetooth audio though.

I am having the same issue. First time experiencing it though; never heard it with the iPhone, HOX, or NS
I'm using a line in cable, and when i jiggle it, i can hear the noise change tone at the same time. I have a feeling it might be because it's a regular stereo cable and the microphone combo jack on the phone is not working right with it. But that's just a guess.
It's pretty annoying and its making the phone unusable as a music player.
Happens in my Lamborghini (Dodge Caravan) when using a MP3 player. Usually, if I run my hand down the cable it clears as though it's some kind of static build up in the cable.

try flipping the cable (putting the aux in side into the phone and the phone side in the aux in) it happens to me sometimes and if I flip the cable it clears it out I couldn't tell you why though. also make sure there isn't any dust in the ports or on the cable ends.
That noise you hear is most likely due to the electrical system in the car. I rent cars all the time for work and never know the shape the electrical sys is in so to resolve the issue I bought a Kensington Cable from amazon and now have CD quality sound from any music app including pandora & spotify.
Hope this helps.:cyclops:

Unfortunately, my cable is RCA on one side (L+R channels split) and regular 3.5mm on other.

Not sure what you mean by "the electrical system" and the "shape" of it. Could you clarify? As I said, I have no problems with other devices in this car.
I would usually suspect something wrong with the car, or maybe a ground loop, but I can plug in my Galaxy S (Captivate) or iPod with the same cable, same everything, just switching out the phone, and the noise goes away.
The way the noise cuts in and out between songs, and when I close the music app, it seems to only happen when the audio chip is getting a signal or is being energized. This is making me think that it may just be a noisy chip :crying:
I was on conf call with SGS3 plugged to AUX, no power charging was going on. And either noise canceling didn't work, or noise was getting in thru AUX line to receiving end. I didn't have problems listening, but ppl on the other end complained, and I had to mute the mic.
:crying:

sorry! Could you speak up please? I couldn"t hear you over the sound of your e-penis
I am having the same problem. My HTC Thunderbolt never had this problem. Same car and cables, I get the hissing and popping until I play something. Then it goes away until I stop the music and then it comes back again. Weird and disappointing.
The problem comes from the 4-pin (TRRS) audio jack in the GSIII combined with presumably bad grounding in my 2007 Honda Accord, or the Aux adapter.
I fixed it with a simple DIY solution. I cannibalized a TRRS headphone jack and bought a TRS (3-pin) port from radioshack. I clipped off the jack with a generous portion of wire, then stripped them and cleaned them from their insulation (they are covered in insulating dye).
I connected 3 of the wires to the TRS connector, and taped the whole thing up. No more hum.
Also known as Road Noise. Where the power cable and audio input are too close to each other. Electrical current emits a small magnetic field which will hinder audio quality and promote road noise from the alternator.
This is a very typical senario in car audio install, when you run the power cable and rca right next to each other.
this buzzing noise happens to me every time i drive my car for the past 3 years:
solution: turn down the car volume. if you keep your car volume half-way, then you wont hear it as much, or you wont hear it at all.... you can make the phone volume as loud as you want though. also, as you accelerate faster, the noise gets louder. watch, try it.
I just recently received the white s3 for tmobile and I was wondering if anyone has this static noise in the music app, but I thought it was just my phone but it transfers into my head phones and makes the noise as well
Any fixes?

S3 for V here. Mine does the same thing, but the music app doesn't even have to be on. Ive already posted in the bugs thread about this and a few others say they haven't had any issues, so I feel its an isolated incident. I only get it when I plug in a TRS jack. When I plug in a TRRS jack, I hear no static. I'm going out on a limb here and going to guess that the sleeve could be bridging connections in the receptacle. But if that's the case, the hardware/drivers should be able to handle that as I haven't had any issue with my iphone and that was a TRRS receptacle, along with a host of many other phones.

I have the Verizon variant and I get this same static. For me it sounds like a crackling/popping sound. Having the screen on makes it worse. I even get it during turn by turn navigation and through my car's bluetooth audio.
Verizon and Samsung support have been worthless. There are no stores with replacement stock within 100 miles of me.
I have the same issue with my sprint gs3. I'm hoping it's just a software issue.
I had this issue for a minute on my Sprint S3, then I realized that I hadn't plugged the headphones in quite all the way. They looked like they were in, but there's a final little click. Solved my issue.
The issue we're talking about happens on the speaker phone, earphones and even audio through bluetooth

I got my replacement shipped to me in several days. If it were a software issue then there would've been more reports. Pretty sure it's a hardware issue. Replace it asap before your return period expires.

Well I followed your advise and unrooted the phone to get a replacement.they of course didn't have any in stock so it'll be there by Tuesday. The rep played music through a set of earphones he had and no further questions were asked. I just hope the replacement doesn't have a different issue like the ones I've read around here. Even my battery life has been spectacular.
I only have this happen to me when I'm charging the phone as well. Have you tried only having the audio cable plugged in?

I've tried everything I can think of. When it happens while the phone rings I guess there's noting else to do. I even rechecked after unrooting it,downloading the latest sprint update but it seems it's hardware related.
it's not only music playing apps but even others like tune in radio do it as well.
I just tried putting the music on the my external sd card and it doesn't do the popping there. when it reads it off the internal storage is when all the popping begins.
