I would like to know too.
My Huawei Y6-PII Compact is very bad because Microphone is placed on Top! I must keep phone upside down to can be heared ok by others. I would like to boost my Mic level. Please help. Thanks.
This work at least with Ulephone Power:
Go Hardware-Audio_ModeSetting-Normal mode-Mic-Level 3
Normal mode is regular call
Level 3 is for calls, I used value 220
(Speaker mode mic value is 255, which is max)
At least Level 4 is for apps.
I don't know what other values are.
Before adjust, mic was almost useless, now it work like in other phones or even louder.
Default levels in normal mode are:
0=0
1=64
2=112
3=144 calls
4=192 apps
5=192
6=184
7=184
8=184
9=184
10=184
11=0
I also drill mic hole bigger, but that effect was minimal.
So my main mic is broken, as a temp solution I tried changing it to the secondary mic. I followed these instructions.
"Open up mixer_paths.xml, go to the "main-mic" entry under "Analog input devices", and change the "DEC4 MUX" value from "ADC3" to "ADC5". Then, change all instances of "DEC4" to "DEC2" (there should be 3 of them you need to change). Now, scroll down a bit to "Recording paths" and locate the "handset-mic" entry. Change "ADC3 Volume" to "ADC5 Volume".
Save your changes and reboot. The microphone used for phone calls will now be the one located at the very top of the device, right above the front-facing camera. This is also the microphone that is used when speakerphone is enabled."
At first this worked, but now it only works in audio recording apps. No longer when I'm in a call, unless I get on loudspeaker.
I'm on CM 12.1, anyone have any ideas?
This same thing happened to my wife's phone 2 days now. I can barely hear her on a phone call unless she uses speaker phone. The microphone works using google or in Handsent when voice typing. Hope this isn't a hardware failure. I tried uninstalling any new apps.
Running stock software on her phone. Maybe she wore out the mic.
Hi,
Try this. I hope it works.

Hi all, my OP7P, running Android 10, microphone is really bad on handsfree mode (speakermode). when calling people are unable to understand me, and there is a lot of noise.
Are there more people on XDA with this problem?
What might be the cause?
Anyone with a possible solution or anything I can try? ( maybe an option in the engineer menu to change some mic settings?)
I tried a few things, that didn't make any difference:
- disabled OK Google
- change build.prop params:
Code:
ro.qc.sdk.audio.fluencetype=none
persist.audio.fluence.voicerec=true
persist.audio.fluence.speaker=false
use.voice.path.for.pcm.voip=true

I have the same problem. I tried to edit build.prop file too. But nothing changed.
I tested with a sound recorder app where i can switch between bottom and top microphones. But both quality is perfect. Bottom mics do not use noise cancelling, my voice is clear from 10 meters. Top mic uses noise cancelling but the quality is still good.
But if i turn on speakermode people are unable to understand me from 30cm. I think when we are on speakermode the phone uses a higher noise cancelling and that causes that poor audio quality.
I rooted the phone tried several options, but i don't know how to turn off noise cancelling completely.
If i could select a mic to be the default one would be good also i think.
Hi Folks,
story first : I got struggle when using my airpods pro on my nubia red magic 3, sometimes mic is not clearly heared (strutted) by my team, and sometimes is ok.
andddd, mic will working if my hands is away from my RM3 (left hand) - i was debugging first, so got the problem is on proximity sensor.
so i got conclution that this bluetooth is using one way sound to my bluetooth using SBC (not aptx or aac that was i see on developer menu) enable by default.
so dual stream audio is not working on SBC, cause PUBG output target is stereo on bluetooth (hearing step), but using internal RM3 mic as input.
so i am doin add this on /system/build.prop
Code:
# add this on last line of build.prop
gsm.proximity.enable=false
and do reboot.
And my internal mic working as well.
impact : if you have some call, the proximity sensor will not working when your ear is near your phone, so your screen will always turn on.
My device is not root is there any way to fix it
Hi, I've noticed that when recording voice notes on instant messaging apps such as WhatsApp or Telegram, the microphone being used for that is the one on the top (near the selfie cameras) instead of the one on the bottom (next to the USB port) and it records in such a bad quality. This issue extends to all apps, including Google voice search and Google assistant.
I've used this app (https://play.google.com/store/apps/details?id=org.greh.mictest) to test the microphone and it only works with the bottom microphone only if you set it to MIC and Stereo, every other setting just uses the top microphone. Also, recording video with the stock camera (using audio zoom or not) records audio with just the top mic too.
If anyone could test their device (either on stock or custom ROM, it doesn't matter as they both use the same mixer path and audio platform info) and answer the poll either with a yes or a no I would be very grateful.
I've factory reset the phone, checked apps that may be conflicting, etc and it's driving me nuts. Motorola support is just suggesting me to replace the phone, but I'm pretty sure this is a software issue.
I'm on the latest stock update if that matters.
EDIT: After more testing on camcorder, stereo recording works fine, but when choosing mono recording, it records sound with the top mic. This done with OpenCamera. Choosing different input options from open camera shows that when you select "Default input" in mono mode, it defaults to the top mic instead of the bottom one.
I am on lineage os 18.1 currently and honestly had no answer for the poor audio quality of my VNs in IM apps... I even developed a practice of asking about my voice clarity during phone calls. Now I understand...
I am going to upgrade to 19.1. If I find a fix or workaround, I will report back here.
I was just doing a little research. Maybe someone can compile an apk or a flashable zip to iron out this bug if Motorola doesn't step on it...
It appears that the "android.permission.RECORD_AUDIO" for IM apps is linked to "MediaRecorder.AudioSource.CAMCORDER" when it should be linked to "MediaRecorder.AudioSource.MIC" or vice-versa.

Nice find, I was taking a look at the stock mixer_paths.xml and the build.prop file under system_ext and found two things, for mono recordings, the mixer_paths.xml redirects all voice recording requests to the "speaker mic" which is set to record from microphone 2 (the top microphone from my testing) and the build.prop file has noise cancelling disabled for speaker and voice recording, if noise cancelling was active, the phone would use the main mic and use the top one for noise cancelling.
I will report this again to Motorola (the first time they just told me to get the phone RMA'd lmao, now I have mor people to back up my claims).

Hey, here are the things I think should be changed for the issue to be resolved (either try one or the other, not the two at the same time so we can see which one of these fixes the issue, if they do at all):
1) In the file '/system_ext/etc/build.prop':
In lines 37 and 38 we can see that noise cancelling is disabled for voice recording and speaker mode, which means that instead of using the bottom mic and the top mic as the noise mic, it's just using one mic, and it's using the wrong one (the top one), this values should be set to true.
2) In the file '/vendor/etc/mixer_paths.xml':
At lines 2177 through 2187 we can see each mic, 'mic1', 'mic2' and 'mic3' being set to 'amic1', 'amic3' and 'amic4' respectively. 'mic1' is the bottom mic, 'mic2' is the top mic and 'mic3' is the audio zoom mic.
Then, at line 2234 we can see that 'speaker-mic' is being set to 'amic3' ('mic2' according to the previous setting) which makes no sense as 'amic3' is the top mic, this should be set to 'amic3'.
I can't try this because my phone is still locked, but if you're rooted you could try this and see if they do work.

On any custom ROM I have noise cancelling issues: my caller always hears their own voice when I'm in speaker mode.
So I tried to apply the changes you mentioned on LineageOS 19.1:
1) Cannot be done because lines 37-38 are missing
2) I did it by setting amic1 and then amic4, with a restart each time. But it looks like I broke my phone by doing this, as now calling apps just crash or stop working properly. Do I have to do anything else besides just modifying and restarting the phone? Even after setting it back to amic3, calling apps still crashed.
Edit: I had to update LineageOS to finally fix the problems.
In any case, can you share your stock build.prop and mixer_paths?

the mixer paths file is the same on stock and custom roms, the build prop is auto generated so they're different, it wouldn't be a good idea to use the stock build prop in lineage. It's a pitty that the changes made stuff worse. the only thing that comes to mind is to check under /vendor/etc and system/etc for the other build prop files and see which ones have the settings for noise cancelling. I'll extract them from lineage and see if there's anything I can suggest. Thanks for testing tho

For the issue you say, you may be able to fix it by changing some stuff inside /vendor/build.prop
In line 134 change "persist.vendor.audio.voicecall.speaker.stereo" from true to false. If this doesn't fix your issue when calling using speaker mode then I'm out of ideas sadly.

Hi @blckbear ;
Could you share the exact lines (the content) in /vendor/etc/mixer_paths.xml and /system_ext/etc/build.prop which should be tested? I am on LOS20 and could do the check for you by pulling/pushing the files and changing the lines you are talking about, though on LOS20 it is definitely not /system_ext/etc/build.prop ;-)

Thanks for the help, but unluckily changing line 134 from true to false did not fix the issue...

Using LOS20 build and changed the lines as you mentioned:
In /system/build.prop:
Code:
persist.vendor.audio.voicecall.speaker.stereo=false
In /system/vendor/etc/mxer_paths.xml line 3018:
Code:
<path name="amic1" />
The complete part:
Code:
<path name="speaker-mic">
<path name="amic1" />
</path>
Testing the coming days, will let you know the results.

Unfortunately people on the phone are complaining about echo every time when on loudspeaker.
So, back to default settings.. ;-)
