Background noise with headphones - General Questions and Answers

Hi,
I just bought a HTC One X and everything was fine until I flashed a custom rom. On stock there was no background noise when I used the headphones but after flashing a custom rom (cm11) there is a background noise whenever I hear music or when the notification sound is played. When I stop the music the noise persists for about one second. So my first thought was to switch back to stock but also there is now this annoying background noise. I think the noise came after I played with the dsp manager. Is it possible that the dsp manager damaged my hardware? Has anyone the same problem?
Thanks.

[BUG] Crackling sound on calls and music, can anyone help?

Hello,
I am a proud owner of a couple Android Phones since the HTC G1, the HTC Magic and so goes on.
Now I was very excited to get the Nexus S, but on the first day of use, after making all the updates to 2.3.2 and installing all my usual apps, I noticed a crackling sound when hearing music from the speakers.
I can not find the reason of this but would like to know if someone had a problem similar to mine, and if yes, if it was possible to solve it.
There are some facts about this crackling noise that I point as follow:
- The crackling sound is not present all the times. The phone works well when playing shorts sounds like ringtones and notifications. I can hear everything crystal clear;
- When I start to hear a song (tried many different players, all the same problem), or when I am playing a game that uses constant music or sound effects, the crackling sound starts after some minutes of perfect sound (usually between 01:00 and 01:30 of good playing);
- It seems like a irregular white noise, like playing a corrupted MP3 file, that gets in the middle of the media;
- It beguns with a low volume compared to the media and gets louder as time passes, until it gets more frequent and as louder as the music playing;
- At first I thought of a broken speaker, and checked the headphones, but the crackling sound appears when listening music on both headphones and external speakers;
- Then I noticed the crackling sound appears on long voice calls too.
Well... I thought it could be something related to the software, so tried the OEM recovery process (Settings > Privacy > Factory data reset), but it was not sucessfull.

Thanks in advance.

I noticed the same thing while listening to Pandora. Not sure what's going on. I'm on Modaco and don't know if its something in there or not.
I hear the noise after about 30 minutes of pandora.
I'm having the same issue running Modaco while listening to music via Spotify.
Just got back to the stock ROM, I'll see if it's any better and keep you guys posted.
I can now confirm that stock ROM is not affected by this issue.

Static sound after playing music on speakers

After playing music on speakers, and sometimes after disconnecting the headphones, I can hear a static sound coming out from the speakers. I don't know if it's a dsp manager problem or just a rom problem. Somebody with same problem? It's normal this sound to be heared for some seconds after stopping music, but not all day.
This drinks the battery very very fast.
I've kph with cranium rom.
I'm using the xxkph + cranium ROM 3.1(fix). Until now, i did not face such problem that you have. Been playing music through speakers and headphones, playing videos. No static sound. Afraid you left some steps before fully installing the custom room or cf-root.
Are you sure? Do you use the dsp manager?
Play some music on your speakers and when pausing it put your ear very close te the speaker and tell me if you don't hear it please.
I moved from froyo to xxkpm based custom rom & had this problem,found the source of the problem to be dsp manager so removed it & sound was gone. It sounded like ta, tich, ta....ta..tich. It was annoying when sitting in silent area, 1st noticed while sleeping something was making sound but could not figure out what next day I found out that speaker remains ON even when phone is not in use & it makes this funny sound.
I will flash back stock rom & test if this is indeed a problem with stock rom or custom rom.
Yes, I have the same sound. I will try removing DSP Manager. What a shame, DSP Manager is quite good, do anybody know something like it? I have PowerAMP but it has just a equalizer.

[Q] Sound crackling?

Hello guys,
I have One S from Tmobile. I use Bluetooth to stream music to my car. My problem is there's a crackling sound in background while the music is playing. When I was unrooted, completely stock using ICS, I still had this problem but the crackling was much more toned down and didn't really interfere with the song. Now, I'm rooted and flashed Trickdroid 9.0 (Jellybean) and the crackling sound is unbearable. The music is impossible to hear now. I noticed this with all Jellybean Sense-based ROMs. It happened with Viper ROM as well. Then, I tried Baked Blackbean and the crackling sound is gone. When I go back to any Sense ROMs, the sound is back.
Now, when I'm calling via Bluetooth, there is absolutely no crackling sound. As soon as I play a song, the crackling sound is back.
Do any of you experience this? I really want to use Sense ROM, but I constantly use Bluetooth to stream music so the crackling sound is a deal breaker so I'd really appreciate your help.
Thank you for reading
Bump! Looks like nobody else has this problem. Any help is appreciated. Thank you

Phone call echo, no background noise cancellation during calls.

Hi,
I have a G920I which is running Mipa atm, I've also tried running, LOS, RR, Frankenstein all with this same issue of other people hearing themselves echo when on the phone with them.
I've tried looking up whatever I can and from what I can tell it seems to be that the background noise microphone isn't suppressing background noise and is somehow picking up the sound coming through the speaker. The only temp fix I have at the moment is to use wired headphones but was hoping for a more permanent solution. Any help appreciated!
