Mic not working during call

I've been experiencing a very frustrating issues where the mic is not working during phone call. I can hear the the other person but they cannot hear me, and if they can it's very very low, so low that they can't make out what I'm saying.
However, the microphone does work again if I go to speaker-phone mode. So i know the Mic itself is working (sound recorder works also).
I think somehow the phone thinks a headset is plugged in and disable the mic unless I'm on speaker-phone mode.
I don't think it is a ROM issues as I have tried a large number of different ROMS, including flashing stock OPO image. None worked.
If anyone know a solution to this issue please help me out. It's very frustrating that I can't make phone calls and have to turn on speaker-phone or use a headset.

Try a different Kernel, had the problem with my 3 different Headsets, i tryed the same ROM with some different Kernels and with the AK Kernel everything worked fine...not with the Furnace! Also try to flash UKM over a Custom Kernel. Check out the AK Kernel there you can find everything you need. If you have done everything right as in the "manual" open up Synapse...there is a point called "Sound", there you can find the point "Microphone", volume it up and try again. if its still not working make a full wipe that your device loses all data and reinstall the original CyanogenMod 11s with this tool here or any tool you want!

If its still not working delete again everything with the tool, install the CM11s with this tool again, install the CWM Recovery, flash the crDroid Rom (best ROM and everything works for me!), flash GAPPS, flash AK Kernel and last flash UKM!
This is my current setup and everything is working

No luck here. : /
I've tried everything from flashing different ROMs to flashing different kernel. I even went back to factory reset, lock/unlock bootloader to wipe device. None of that work. Very frustrating. I'm starting to think it's a hardware issues, since trying out that many ROMs didn't help at all.

Did you informed oneplus already?

Yep, filed a support/warranty request. But god knows how long it'll take for them to get back to me. There's no phone number support or anything. : /

Hi,
unfortunately I have the same problem. I've tried to fix it even modifying the system/etc/mixer_paths.xml but nothing works (http://forum.xda-developers.com/one...icrophone-ok-google-low-t2805568/post53914918). I noticed when that changing the values of hph-mic and anc-mic to 0, then handsfree mode doesn't work neither. Therefore we have clues to think the main mic is which has the problem.
Curiosly, I do not have had this issue out of the box, I think it began after 30O update. However I've downgraded to 25R and the issue remains.
I hope you the best luck
Regards

Cynogen 11s team is working to add support for CTIA headphones soon. See my post in similar thread (http://forum.xda-developers.com/showpost.php?p=55186894&postcount=25)

OK figured it out I uninstalled the latest hangouts update and made and received several calls all seems to be ok now

Is there any update regarding this issue? I still have this mic problem during calls and no clue on how to fix it.

OPO microphone problem is a hardware problem
Same problem here.
One morning main microphone in my OPO died - no one can hear me during call.
Recording sound with main mic gives some barely audible sounds.
tried reboot/factory defaults /root with fixing mixer paths - to no avail
The only solution is to call with speakerphone or bluetooth headset or normal headset.
Looks like hardware problem. Sadly OPO support sucks.

I have a similar problem. Did you find a fix? I did everything. Restarted, ROM changed and everything!

As I wrote - no fix - IMHO it is a hardware fault. Still waiting for response from OPO support in hope for receiving RMA.

I am also thinking to return the phone because of this issue.

Just adding that I also have this problem - phone was working fine until yesterday.
Now mic is extremely quiet in call, unless I switch to speakerphone then it works fine (Video recording sound is fine also, but Google speech to text etc is not working)
I installed Swiftkey last night but I think its unrelated

Has anyone found any solutions for this problem yet?

Yes, I sold the phone!

:laugh:

I´ve opened a ticket. I advice to do the same.
- They will send you a link, with the ZIP-file in this link you have to reflash the rom. But probably it won´t work.
- Then tell them that it doesn´t work (of course only if it doesn´t work).
- Apply a RMA request
- Send them your ONE
- Receive an new one.
I´m waiting for the TNT courier, at the moment.

same problem here. No response from support. now recently even the emails to [email protected] are bouncing back with error, cannot deliver your email to the address.

So.. I'm having the same problem now..
I can't even submit a RMA, as I bought the phone from a person without the invite - so I have the receipt and everything, but when trying to submit the RMA, I have to select the order - Which I have none of, isn't that just wonderfull?
Did any of you find a solution?
I've had Samsung GS3 and GS4 with almost the same issues now and it is killing me, my will to keep living with these problems are close to none...

Can't hear any audio during an incoming call

I am using a non-rooted stock rom based Moto G 2015, XT1550.
Sometimes when i accept a call, I can't hear anything but the caller can hear my voice perfectly, that is the mic is still working.
This occurs only once or twice during the day and only when somebody calls me. Unfortunately the 30 day return/replacement period is over so I can't return the phone and my network receptions seems to be ok.
Theses are the steps I have taken to try to resolve the issue on my own but without any fruitful result:
1.Tried factory resetting the phone.
2.Wiping cache partition
3. Rebooted the phone
4.When this issue occurred tried plugging in the headphone, switched to the loudspeaker,
placed the in-call volume to the maximum but none of this produced any audio output.
5. Tried testing the earpiece using the service mode *#*#2486#*#*, worked OK.
When I faced this problem I wasn't listening to music or using any apps(like if the audio was routed to the headphone port and not switching back to the earpiece).
6.This happened before and after the recent stage fright update.
7.Disabled OK Google detection.
8. Moto assist was also off.
My data and bluetooth are always off, I am not using any new or unfamiliar apps that might cause this issue. Could this be a hardware issue? Please advise me on how to fix this issue...Really need your help :crying:
If I could find any fix I will update this post soon.

Try flashing the stock firmware, maybe that helps it.
(Warning: downgrading can cause problems)

No audio through speakers, no phone calls audio at all

Hello guys.
My device is Nexus 6.
After a while when i had random reboots here and there, i decided to clean install the rom again, so i formated my sd card.
Later on i did the simple steps of installation, rom, gapps, root, kernel etc..
So everything is great right.. Yeah well after getting my google account's apps back from the cloud and some minor usage, i realized i have no calling audio whatsoever, even if i press speaker or use earpads, only sound i hear is the disconnecting beep when i press to disconnect.
Another weird thing, others can't hear me either.
So what i did is simply trying to clean install other ROMs with the same result..
As of now after like a full day of installing and clean flashing, i am on Ressurection Remix ROM, with ElementalX kernel, ive also tried an older version of the kernel.
At first i have installed all Gapps, then kernel, and then checked, it was all fine. (could call no problem, no sound issues)
I have installed DivineBeats, listened to some music with viper4android + Dolby+ all great..
So i had to make a call, and realized it does this thing again, no sound at all on calls unless i hang up and hear only the short hangup beep.
tried ofc rebooting and clearing cache/dalvik cache with no luck, i also realized i have NO SOUND at all throught speakers, wether its media, typing or anything, with earpads however i do hear media sounds just fine.
Please, i don't know what to do.. a phone without a calling option or sounds.. is just unusable..
Thanks ahead ://

Little update, flashed FrancoKernel r73 (latest).
I do have media and typing sounds..
NO phone calls audio whatsoever, doesn't matter if i use earpads, earspeaker or speakers, can't hear anything but the disconnecting beep.

Tried disabling apps, tried Safe Mode..
Still no audio when dialing...
What could possibly cause ONLY the dial to lose functionality?

Bluetooth Phone Calling

Hey all,
Its been a while when I couldn't make any phone calls using any bluetooth devices, non work; car, headphones, loudspeakers with mics even with the phone toggle on in bluetooth settings. This started before the first beta of P, sometime after purchasing the device.
I know that there are some bluetooth problems with some people on the pixel and Android Oreo and Pie but couldnt find any information if these problems are solvable or not.
I installed the official Pie update today and the issue has not been fixed, does anyone know if there is a solution to this or should I wipe the device clean and start over?

I have no issues. I'm using the pixel 2 straight from Google, on verizon. Make sure to do a clean wipe when upgrading to Android P, not a dirty flash.
I downloaded the factory images (not OTA), flashed the update script in Windows which wipes everything by default. I then rooted using Magisk 16.7.
I just took a phone call using phone speaker with no issue. I then used my sennheiser momentum wireless bluetooth headset to call my voicemail. No issues, and sound quality is great.
So yeah, make sure to do a clean wipe on the update. I recommend the latest factory images and not the OTA. Perhaps maybe your radio and/or vendor images are mismatched? The latest factory image will make sure everything is in sync.

Microphone not working...

My Google Pixels microphone randomly died after some point in its lifespan, but happened recently. First i updated version to Android Q Beta 1 (and it was working all right on that version) but when i updated it to Android Q Beta 2 (microphone stopped working and whole UI experience was buggy, some apps not working, random restarts, etc...) but then i got it back on Android Pie, and it worked for few minutes into boot and died yet again... Then i installed custom ROM (Pixel Dust) with TWRP recovery and Root, but nothing of those helped, then i got it back on Android Pie via adb sideload OTA. That didn't help either... So i don't know is it the software problem (because it seems to work first few minutes after i boot it) or is it the hardware problem. I use my phone mostly for phone calls and now because microphone is dead, it lost its functionality... But speaker was working,earpiece and 3.5mm jack.. Any suggestions??

i'm having a similar problem at the moment. Since the April OTA update, phone calls stopped working. Even when using a BT headset. I tried reverting to Full Recovery Image from february, but that only helped a bit. Also, any other audio app was not able to use the speaker. With the Feb version, youtube and google music were back working, but phone calls are still not possible, causing the telephone app to freeze. I was thinking about installing some custom rom too, but that doesn't seem to do the trick. Did you try to wipe the cache in recovery?
Update
found three possible workarounds for people having the same issue, perhaps one of those helps. I'll go through them today evening.
You could try enabling the "Disable USB audio routing" in developer options and see if that works for you. It did work for me

Change your launcher, for example, on nova launcher, disallow permission to microphone for google app and never let him this permission, do not use google assistant.

Maybe is a kernel error..but definitely is not a hardware problem. maybe try changing kernels. o downgrading to 7.

since none of the above tricks worked in my case, i booted TWRP to clean the caches. Didn't bring any good result. So i flashed ElementalX Kernel and now i got some kind of a better result, even if it's still weird. Everything works now except incoming calls. I can actively call other persons, use whatsapp or facebook audio calls and all is good. Only if i receive calls, still mic is muted.

I will try everything from above, and hopefully something will actually work and get my Pixel back in life. I will get you updated guys.
Thanks for the support.

None of those helped so far, i'll try flashing some kernel then...

I discovered that when i try to record with my camera video, it says "Can't record audio. Another app is using the mic." Also when i try to record audio message on Messenger app, as soon as i click on microphone icon it says some error.
Update, my sound and video won't record, both on Youtube or Instagram or any kind of video audio playback.

Update
I flashed ElementalX kernel and same stuff happened, phone calls and microphone was working for first 30 minutes then it got back to old days, not working as usual. Now i think this is hardware problem

have you tried chaging vendor image, or getting a vendor image from a working pixel?

I installed lineageos 16 without gapps and is working good for hours until installed gapps.
