Nexus 10 Microphone / alternatives?

Hi,
I've had a lot of trouble with the in-built microphone in the Nexus 10. Whether using Skype, Hangouts or other VOIP apps the sound is best described as muffled as if I am in a large room and a distance from the microphone. I through at first my case may have been covering the microphone but removing it has not effect. Then I found https://code.google.com/p/android/issues/detail?id=42263. Unfortunately, there seems to be no solution. Has anyone had any luck improving microphone quality or getting Android to switch the default microphone?
Failing that, are there any decent substitutes? Do generic usb or bluetooth headsets work?
Thanks,

I have been having the same issues with my mic too. Really seems just like a bad design and placement. I was looking for some kind of app to some how boost the mic input, but there is none. I use a stereo Bluetooth for most of my needs but I always don't have it around. If you figure or anyone else does out any other type of fixes please post.

Yeah, I'm begging for a solution, too. This is just a damned stupid bug - and the fact that neither Google nor Samsung feels responsible for it is just sad.

We are in the same boat people. Maybe this could be resolved using custom kernels?
Could anyone please have a look into this? I'd be infinitely grateful!

Downgrade
I had this same horrible microphone quality in Skype problem with Lollipop 5.1 on my Nexus 10. A factory reset didn't help.
The answer: Downgrading to Kitkat 4.4.4 from the Android Developer's blog. Perfect microphone quality after that.
Not a great solution, but works until Lollipop is fixed.

[Q] help!! nexus 4 low mic volume during phone call,

Guys I need help in fixing my inbuilt mic. Volume is very low and friends on other side are unable to listen anything. Though it is working when I use Skype, viber or recording.
This happens few days after upgrading to KitKat and didn't solved after 4.4.2 upgrade. Let me know how to fix this.
Thanks in advance!!

Got the same issue
Just thought I'd chime in and say I have the same problem after the update to KitKat... Bummer
When recording the voice with whatever software there's no issue but callers say I sound very low/very far away from the mic. No difference between using the phone's mic or using a wired headset. Have yet to test a bluetooth headset (I do not have one).
I'm on Nexus 4, stock rom, 4.4.2. Any tips or ideas would be appreciated.

[Q] {ISSUE} Nexus 4 - Microphone does not work on normal mode, but works on speakers

Hi,
I've been using Nexus 4, and recently this issue started.
when I try to call, the other side can not hear my voice.
However, if I turn on the loudspeaker the mic works fine.
So, the probably the hardware is fine because the same mic works fine when used in loudspeaker mode.
I've not installed anything, not changed anything, its a brand new device.
I've tried starting in Safe mode, it doesn't help.
i was using the stock android from google all these days and issue started. I have now migrated to Cyanogenmod 11 and the issue still persits.
I have downloaded an app from play store called soundabout to try convince my phone that there was no headset plugged in. But of no use yet.
Any help on this please

Help please

Fellas, please please help

Does your earpiece speaker work normally? If so I can only guess the nexus 4 uses top mic for loudspeaker calls. If your bottom mic has failed its easily fixed as it comes as part of the charging block.
It could just be something blocking the mic. Does your voice sound muffled or is it no audio at all?

Yes the earpiece speaker works fine. the bottom mic if u hold it close to ur mouth and talk works just ok...as in the other person cant hear 100% but its like u r talking from a far off place.

Hardware problem, mic - flex cable???

Probably is just dust or something then, get a dental pick or something and try and clear the mic hole from the outside. If it still doesn't work you might have to disassemble the phone and remove the blockage.

I had the same problem and I use the application soundabout to resolv it

Nexus 4 MIC not work - all answers listed

Primary mic broken, is it possible to redirect to secondary mic?

Hi all,
I am having problems with calling since i bought my n9005 4 years back, people did not hear me speak on the other side, but when i put the phone in speaker mode the sound was just fine on receiver side.
Using different roms from stock to CM13 and miui nothing software related seemed to be the problem (tried all the things that i could find on the net and in settings).
Anyway, so I always been calling on speaker or using my huawei watch.
Now after all this time i thought lets fix it, and bought a new USB / Mic unit which i installed without success.
Since on speaker calls still works great, normal calls only cracking sound, i thought maybe its possible to redirect thru software to secondary mic on top of phone which i believe gets activated when talk on speaker phone?
Thanks in advance.

Mic not working during calls (maybe broken mic) How can I switch mic via mixer_paths?

Hi there everybody. First time posting anything in any forums. Please excuse any irregularities that I may show (deviating from the norms and such).
ISSUE BACKGROUND
So I recently bought a LeEco Le Pro 3 (LEX727) second hand and I've run into an issue with the microphone during calling. I can hear the person calling fine, but the caller cannot hear me. I have checked that it is not a sim issue as I've tested call with two different sims (one local and one international sim). Currently it is running on LineageOS version 15.1-20180312-NIGHTLY-zl1. It is currently rooted via Magisk.
In system/etc/usf/form_factor_mtp.cfg I found out that there are two mics:
- top right mic
- bottom 90 degree mic.
I confirmed the top right mic is working as Google Now and recording apps picks up my voice. Using the MicTester app, I also confirmed it is indeed the top mic is functioning fine as the sound wave increases in amplitude as I input sound closer and closer to the top mic (as opposed to the bottom one).
I feel it is not a software issue as I have flashed various roms to the device, resulting with the same issue. Roms I have flashed includes:
- AICP (Oreo)
- Stock EUI
- Resurrection (Oreo)
- LineageOS (Oreo)
- Lineage OS (Nougat)*
*note: the phone came with LineageOS in Nougat. Same mic issue
Flashes were attempted with factory reset only and with complete wipe of internal storage (this was the latest attempt)
Also attempted to use MicFix module for Magisk. Still no mic
Also tried muting/unmuting during calls. Still no mic.
Also tried toggling loudspeaker on and off. Still no mic.
Hence, I feel that it is a hardware issue. To strengthen that opinion, there is a one solitary dent on the phone, near where the mic would be. Could be a completely busted mic or disconnected mic.
Also calls works fine via a connected wired earphone with inline mic.
CURRENT PURSUED SOLUTION
To remedy this issue, I wanted to reroute the mic paths for calls. Instead of using the bottom mic, I want to use the top mic instead. So could I get some assist in editing the mixer_paths.xml file of this phone to achieve that?
I found there are a few file with the name mixer_paths
system/etc/usf/mixer/mixer_paths_mtp.xml
System/vendor/etc/mixer_paths_tasha.xml
System/vendor/etc/sound_trigger_mixer_paths.xml
System/vendor/etc/sound_trigger_mixer_paths_wcd9330.xml
There is also this file:
System/vendor/etc/audio_tuning_mixer_tasha.txt
Can anyone help me figure this out with me?
Also, if there is a better way to solve this or that maybe the direction of editing mixer_paths is not quite right please do tell.
Note: I am not adept at codes. I have done a semester of matlab and c++ and that's it. Not really code savvy.
Any assist is very appreciated. Have been troubleshooting this issue for a few days now. Can't seem to be able to solve this

Hmm... I don't know if you'll get the help you need here. You should also try posting to reddit.com/r/AndroidDev, or maybe the general XDA Q&A forum?
What you might find easier to do is just replace the mic entirely. The mic is located at the bottom of the phone, on the charging port module itself. Replacements are available on AliExpress, but they might be missing some features(?). A few other users have the same problem as you. I encourage you to read through this sub-forum.

I'll try with ur suggestion to post this elsewhere. I'd rather not replace the microphone just yet because I'd like to try a non-open-my-phone-apart solution. Not the most dexterous of hands.

use a headphone/bluetooth mic till u fix it

I have a different device but the same issue. Main mic is not good, gives nothing but hisses.
Tried using RuleBot(info.kfsoft.autotask) from play store to automatically enable loudspeaker (which forces microphone to switch) when there's a call. I will update later if it works.
