Well I just bought my self an Galaxy SIII and I'm loving it but I'm having a little problem with the headphone jack.
I plug my phone everyday to my car stereo for music and there comes like this pop and cracking sound while I'm playing. Doesn't matter if the stereo is at high or low volume.
First I thought it was my audio equipment in my car but then I gave it a go in another car stereo with an different lead but the noise is still there so it is the phone.
Is someone else experiencing this problem or is this a faulty unit?
I tried searching for same topic here but couldn't find anything about this.

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.

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!

Mine changes pitch according to my cars rpms

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.
Hey I own the i9300 and for a while my audio has been very quiet, to the point where I had to put my ear next to the speaker to hear anything, and the odd thing is only earphones with one cable instead of two joint ones coming from the jack will work. I've replaced my speaker earlier and it's no different. Does anyone have any idea what the problem is? Sorry for the poor explanation.
I've been searching here and in other forums about this issue that I'm having and I'm not sure if someone else is having the same issue.
I have 2 earphones, one is the one that came out of the box (HTC with black flat wires and red earplugs) and also bought an HTC urBeats headset (red round cable with heavy metal black earplugs).
Every after a call, there's a loud static cracking sound that happens and it's getting pretty annoying specially when you had the call in the highest volume.
Is there anyone experiencing this? Is it a unit issue, software issue... need help!
Yes!! So far as I can tell, it only happens with HTC wired headsets. In my case it started happening suddenly about 3 weeks ago, and I thought it was related to using an old car charger that had a faulty connection. I've had my M8 since it was released, and originally was just using a fairly cheap set of Sony miked headphones, and never noticed the (to me) painfully jarring screech noise upon disconnect until I used the HTC ones that came with the phone. No static with Jaybird Bluebudz Bluetooth headset. I don't know what is causing it for certain though.

I noticed that it does not happen with bluetooth connected devices. I have a Jlab Crasher and calls works well too.
Has anyone tried other earphones? I'm wondering if it's isolated to HTC earphones or wired earphones in general.
With mine, I just confirmed it happens on all wired headphones, not just the stock ones. Initially it was just on the OEM headphones. Another thing that happened on both the OEM and my basic mic'd Sonys is that it will disconnect the call I'm on. I hope I don't have a defective headphone jack. Really don't want to have to return this thing.

I've got a strange one where when connecting a Z3C to the aux input on my Ford Falcon there is a loud crackling noise from the car speakers.
I've tested with other phones like iphones and samsungs and the sound is clean without issues.
Tried connecting a friend's Z3C and the issues occurs same as when I connect.
I have tried different aux cables and played with the settings on the phone and the car but can't seem to resolve this weird one.
Can anyone shed some light on what else I can try please?
Oops wrong sub my bad...mods please delete.
