Hi all,
first of all sorry If I posted in wrong section. I know that there are a lot of thread about this problem and this is the reason why I'm so confusing.
The problem depends on a lot of conditions.(kernel, Rom, external hardware etc. and seems depends on AGC, so the fix should be simple. i.e. decrease gain of microphone):
try to record a video during a live event (or at home from your stereo with high volume) and you will realize that the audio is horrible, crap and distorted. What I already tried.(with stock rom 4.4.2 )
- Stock kernel, Stock camera app, internal mic -> horrible
- Stock kernel, Stock camera app, iRig mic cast-> not working
- Stock kernel, Lg camera app, iRig mic cast -> should solve the issue (but last lg camera app version is very old )
- Faux kernel (last version), FauxSound (last version) ->Try to adjust the gain -> doesn't work with stock camera app (it seems the app reset the microphone gain)
Anyway my device shut down randomly (loosing the synchronization with google account) using faux kernel
So if you read till the end of the post .. Anyone definitely solve the issue?
I mean changing kernel, ROM, using some external mic , replacing stock camera with different app.
Please help me understanding your device configuration if you already solved
Thanks!

Hi Guys,
I've seen other threads about this issue with the mic gain being set too high on the nexus 4, but all of them resolve the issue with Faux Sound or something similar that uses a custom kernel. The problem is I'm running CyanogenMod 10.2 latest nightlies, which annoyingly don't let me use Faux or Franco kernels... or any others that I can find for that matter... So, is there any way that I can adjust the system mic gain whilst still keeping CM?
For anyone not aware of the problem, the audio is recorded very distorted in most apps, including making a skype test call, so probably in-call as well. The only app unaffected is Tape Machine by Samalyse, as they seem to have figured out a way to adjust the mic gain in app.
If I can't get it sorted I guess I'll have to figure out how to get stock android 4.4 on my phone with faux kernel...
cheers!
Hey guys i have problem with my mic, can only use in calls. In other apps like whatsapp, video recorder, voice recorder the mic don't work. I have this problem with all the ROMs i use. I hope you can help me. Thnks :fingers-crossed:
I have the same problem on v20 baseband with all roms I've installed. There are several people reporting same issue. Some time ago I've rolled back to v10 baseband and stock ics rom - everything was working fine. Installed recently v20 baseband and kitkat cuatom rom - problem reappeared.
However if you plugin headphones mic is recording correctly in all apps: sound recorder, camera, etc.
If anybody has an idea how to fix it, please share.

during logcat session i've did these actions:
1. turned soundrecorder and started recording, then played recorded sound (only noise was heard)
2. turned camera and recorded video
3. plugged headphones when applications were minimized
4. repeated point 1 (only noise was heard).
5. unplugged and plugged headphones again when soundrecorder application was running
6. repeated points 1/4 (this time everything has been recorder well)
7. repeated point 2
8. played first 2nd video from camera (everything was recorded fine) then played 1st video from camera (only noise was heard).
9. if i would unplug headset and record anything again only noise would be heard.
Cheers.
So the problem is that no matter what custom ROM I use the mic volume is incredibly low. Talking on the phone I cannot be heard at all, if I put it on loudspeaker I can be heard faintly. Same problem for any app that uses the microphone, like sound recorder, recording a video, it barely picks up any sound.
But what's strange is that everything works perfectly on on Stock. I've installed custom ROMs on this before and last used cm10 before I upgraded way back. But now the problem also exists on that CM10 ROM. Any ideas how to fix it?
Additionally I've tried disabling the google now search listening (which fixed the same problem on my OPO) but does not work here. I've tried the following ROMs: CM10, CM11, CM12 all official nightlies and Crdroid 5.1.1.
Very frustrating as otherwise CM12 works perfectly and I intend to give this phone to someone!
So testing it further I found out that it works fine using google now and search. So either the internal microphone is disabled or maybe noise cancelling is messed up.
People lately tell me, that my voice sounds distorted/echo/metallic when talking on Whatsapp or via the regular call app. That behavior ceases, when I press hands free button for a second for external speaker and press again, to use regular phone speaker.
So it seems, it's a software problem not hardware.
I checked in Dorimanx Kernel, there was a mic gain of 30 enabled. I switched that to 1. Also used Faux instead of Dorimanx Sound controls. Applied, rebooted, but no change.
Does anybody know, what else is could be? Or with what settings I could fiddle? Thanks guys!
Do you have the problem with stock kernel and/or rom?
I use this rom/kernel combination for ages... Didn't flash anything in over a year or so... But the sound distortion only seem to have started recently...
Hi, I tried the kernel 3.4 on my nexus 7, but after I installed it my speaker starts to play audio really bad, now is noisy ,scratchy and pretty low. So I tought was rom/kernel related, and back to 3.0 kernel, but no way to get it working good again. So I changed the speaker with a new one, and the audio isn't anymore scratchy, but is really low when compared to his previous stage, I cannot use in a room with peaple simply talking for example, forcing me to use a bluetooth speaker, or headphone. What happened to my nexus 7? I changed many roms, but doesn't seem to be fixable by sw, what can I do? now I'm on slimkat + parrot mod, which works flawlessy.
thank you
