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...

[Q] Dialtone issue for Outgoing call on bluetooth -Android 5.0

Hi all,
As the title suggests, everytime when I am making a call on blueooth (car), the ring\dial tone will stay silent for the rest of the process until the call is connected. I have also looked into the settings menu under sounds but with no help, tried deleting and repairing the devices and no luck. Is anybody else experiencing this problem and better yet, found a solution for this?
My friend is also experiencing same issue and we are using Ford car Bluetooth connection.

Also happens on my Nexus 4 newly upgraded to lollopop.
Fine for incoming calls but silent for outgoing. Switching to speakerphone on the device then back to bluetooth seems to manually make it route the call through the bluetooth handsfree but is obviously very unsafe.
Suprised more people havent mentioned this issue!
Managed to find a fix? 5.0.1 doesnt sort it sadly.

Finally I see someone acknowledging the issue.
Nope, could not find any fix and surprisingly no one is mentioning this issue anywhere. Experts in this forum should help us with some solution.

Got the workaround

You can put the source of the audio system to Bluetooth audio and you should be able to hear the dialtone. Afcoure your call end buttons on audio system will not work while on dialtone. After the phone is picked-up the buttons start working

Do you have other devices paired to your phone? If so, you might experiment by UNpairing other devices (headphones, bt speakers, whatever) and then try again.
I've seen my go both ways. But I prefer it paired with my car so have tried to limit the bt pairing between my phone and the watch to notices and some data updates but NOT voice.

thanks for your answer. i've tried this, doesn't work. i've also reseted my watch already and reinstall all the samsung stuff. not working at all.

ive fixed the problem so far. its caused by the rom, if i use the oxygenos it's working

I can confirm that there are a few custom roms (7.1.2) which supports the calling functionality in OP2.
You don't really have to move back to the stock Oxygen OS. :good:

HalogenOS
AICP etc..

Google Pixel No Sound issue

Guys, this issue has been pestering for a month now and I seem to have not found a fix for this yet. I first started to notice the problem with my phone when I was unable to attend the calls, the screen will usually get stuck or i will not be able to swipe up the green button during the call. Even if sometimes I manage to i will be able to hear the other person speak but I wont be able to speak to them. So sometimes once I restart the phone it will seem to work fine for an indefinite period of time and again it starts.
Then things started getting very bad, sometimes during normal device usage, the screen just turns to a monochrome black and white screen ( just as you see when there was no signal on older television sets). And when I switch to the bootloader screen, when I power the device on, I get a very thin green line for an instant on the screen and then the booting sequence starts.
I have made a lot of factory resets and stock image flashing, and by far I noticed one considerably situation, the times when the sound functions fine, the booting sequence where the 4 google dots animation appears and when there is no sound, the booting sequence gets stuck on Google and made by Google screen.
Other observations are during abnormal device behavior, no function related to sound will properly. To elaborate it, Google assistant wont work, videos cannot be played and even the system sounds wont be heard. I am open to suggestions here. Please let me know what can be done to test the phone out. FYI I know there is a problem with the Pixel microphone, but I am not convinced that its the exact problem. Please correct me if I am wrong. Thank you.

Sounds like a hardware defect. RMA if possible.
Sent from my Pixel using XDA Labs

It is a hardware issue indeed, I am facing the same issue, I contacted google , they told that replacement is possible tho I'm out of Canada at the moment so I'm just dealing with it through my Bluetooth earphones, everybody works fine with Bluetooth.

That's the only way I suppose!...did you get the phone directly from the Google store?...are they accepting phones bought from a retailer?...since I am in Singapore now...Google support is next to nothing here...try contacting them but it's of no use...only when I get to India I will be able to go forward with the replacement!.....but the thing is .... yesterday...I updated the phone to Oreo and the audio stopped working completely....and after repeated switching between safe and normal mode....the speakers are working now...but the microphone is still busted.

This happened to me, I was given a replacement phone from EE UK

Current update guys...as per the pixel support centre person's suggestion ...I rebooted the device to safe mode to check if the phone is operating normally ...which it did not....but surprisingly ...after restarting to normal mode ...it started working normally again...my query is how is this zeroed down to an hardware issue if in case it's perfectly working for a while and at some point goes bonkers...can you guys please enlighten me on this...coz I don't have much knowledge on the hardware field.

Tough luck mate! Sorry to hear that....you can check it out by pressing down the power button until you get the power off and restart menu. Keeping pressing down on the power off menu...it will reboot to safe mode without your prompt. In safe mode for me it was the same....maybe you will have a better luck...try it out!

well, its been almost an hour the phone wont turn sound back on.

Keep switching it to and out of safe mode...at some point ideally at least the speakers must start lest the microphone. Tried contacting Google about it and no response at all...mine started acting weird only for the past month...I suppose from the Aug months patch update....tried reverting it back to previous stock versions...but I suppose the damage is permanently done

When I contacted google, they told me to send it back to Canada and let someone there give it to google.. which won't happen in my case , my phone also started acting like this after Oreo beta . Now I will restart the phone whenever it happens to get it back working :/

The only reason I am still sticking to this phone is coz of it's camera. Planning to get back to India around December to get this fixed. Support for pixel in Singapore now is next to nothing since it wasn't launched here. I had no problem at all with the Nexus line up but this is kind of a disappointment.

You've mentioned it as through Bluetooth it works fine....care to elaborate on this?...are you able to input voice commands to Google assistant and speak over calls using it ?...since I am planning to buy one in case its a perfect workaround

Yea, Bluetooth works fine for calls, as for google assistant voice command you can enable that from google app settings. Of course other media will be working with Bluetooth as music, YouTube, etc..

Hmmm I don't remember connecting to a laptop via Bluetooth.. you mean for file transfer ? Anyway Bluetooth has nothing to do with the sound issue we are facing, it might be your laptop Bluetooth driver needs to be updated

Planning to do just that....I may have better luck with a custom kernel...will post an update once I have flashed it.

I had been on the 8.0 beta for a while. Then got 8.0.
Though just 2 days ago, my mic was starting to have issues. Then yesterday, only my speaker phone would work.
Now I can't get any audio/mic except though Bluetooth (I've got a portable speaker with a mic, and Bluetooth on my car.
Contacted Google support. Will be getting a replacement on their warranty.
They didn't tell me this, but I did some searching, and apparently many of the pixels (mostly from the first 3 months of production) had an issue with the soldering of the audio codec. though usage, little bumps here and there, that soldering can get loose. Which explains why my audio and mic were spotty, and within an hour yesterday morning, all aspects of it stopped working.
So, it's a hardware issue.

LineageOS - No sound in voice calls (speakerphone only)

Hey folks, I installed Lineage OS 16 on my HTC U11 recently (unofficial version as the phone isn't officially supported) and had the known issue that there were no sounds in voice calls (I couldn't hear anyone and nobody could hear me). I successfully fixed the issue by editing two lines in the build.prop ("persist.vendor.audio.fluence.voicecall=false" and "ro.vendor.audio.sdk.fluencetype=none") as suggested by some threads in this forum.
Lately while my phone was connected to my car via bluetooth and I got a call (speakerphone), I had the same issue as mentioned above, no sound at all. After that I disconnected my phone from my car, deactivated bluetooth and called back, but the problem persisted and there was still no sound. Then I restarted my phone, called again and everything worked fine.
This happened a few times now and only when I called somebody or received a call while the phone was connected via bluetooth to an external device. It's very annoying that I can't use my phone via speakerphone anymore and that I have to restart the phone everytime after I received a call while I sat in the car.
I hope anyone has a solution for this and hopefully one that doesn't include the reinstallation of Lineage OS
Thanks in advance.

It sounds like you have the pie firmware while this rom is with oreo kernel. Anyways you can go here and try this fix https://forum.xda-developers.com/showpost.php?p=80620553&postcount=1267
