Mic not working for voice calls (works for google voice search and speakerphone) Mi4i - Xiaomi Mi 4i

Hi all,
I'm having a problem with my mi4i when I have voice calls the microphone doesn't register any sound. It works fine on speakerphone and on doing recordings which leads me to believe this is software and not hardware.
I've tried removing the google voice detection stuff by inhibiting it, as i saw elsewhere this was a problem. I couldn't find any options about noise cancellation which may be malfunctioning.
I'm currently using the most up to date MIUI rom (MIUI 7.0.3.0, android version 5.0.2 LRX22G, kernel 3.10.49) but was previously using the ressurection remix. Both times I had the same problem; I was hoping that with the update to the latest MIUI it would fix this problem, but alas it hasn't.
If anyone has any ideas of how to fix this it would be appreciated.
Also, thanks to all the people out there working on ROMs and fixes!
Thanks

Bluetooth wont answer incoming calls only?

Its always worked updated to Cm11 and now Bluetooth won't answer incoming calls. It picks up just no audio at all and they can't hear me. I place a call through the car or play music they work fine. Did a factory reset and install the latest build for Parandroid. Same issue. Now titanium did do a restore. Would this happen to bring something across if it was buggy on the bluetooth? I can make calls and control everything through the dashboard but just cant answer incoming calls. Tried another phone and works just fine. Anyway suggestions?
Lots of people with CM or ROMs based on CM are having this problem. check the development topics for Cm11, mastodon, aicp, Slim among others. Word is a developer has figured out the problem. Others have changed basebands and solved their problem, while others continued to have the problem. I ended up switching from aicp to liquidsmooth and I now can receive calls via Bluetooth.

I too am having the same problem using CM11 M10 on an S3 LTE. Also had the problem on M9. Please share any solution that you find works.
Folks having probs with incoming calls and any other incoming Bluetooth issue (eg music through external speaker) while on CM11 or CM11-based ROM (eg. AICP, Spirit). My understanding is that CM11 developers have determined the cause of the prob (related to the kernel) and that they are pushing down a fix in the current or upcoming updates.
You can also solve the problem by switching to a different kernel (this is the path I took with Spirit ROM... I switched to current BMS kernel). Make sure to use the correct kernel for your device.

Hi, since i updated to cm12 (now running YNG1TAS17L) the loudspeaker has stopped working when making calls. has anybody else had this issue? i only noticed when the new voice activating update wouldnt recognize my voice.

Not here. Loudspeaker is fine but the voice recognition is crap. Doesn't work at all

Low microphone volume / not working

Hi, I've got some kind of problem with my Mi4c microphone. During calls no one can hear me if I don't use the loudspeaker option, and when I try to record something it's really quiet. I've tried stock ROM, cyanogenmod 12.1 and 13.1. Does anyone know what may be causing it? And what's the fix? Thanks in advance.
same problem
I have same problem to, i've try to change microphone with other, but it still same..
Please help thus isue...
Same problem with me. My partner couldn't hear my voice when we made video call with facebook, hangout, duo etc. But using line working normally
Same problem here. It started after updating CM 13.1 TS to version 20161007.
It looks like other phones are having the same problem, so I guess it's not an mi4c specific issue... As for Skype, 7.00.0.655 works. See https://community.skype.com/t5/Android/Microphone-not-working-android/td-p/4417354/page/4
Extremely low microphone volume when doing Skype Echo call test on stock MIUI8, but works normally when calling somebody. Weird.

LineageOS 16: Crackling sound with voice messages on S7 (SM-G930F)

Hey,
I recently flashed LOS 16 (coming from LOS 14) in order to hopefully get rid of my crackling recording problem.
The problem unfortunately is still there. I don't know if it's a hardware or software problem.
Phone calls are completely fine, however, the microphone makes a really annoying crackling sound whenever I record voice messages or use any kind of voice recorder on my S7.
Perhaps someone has an idea about what I could do. I already did some research but nothing helped.
Is there a way to disable the onboard microphone and just use a headset whenever I want to record voice msgs or make calls?
I'd appreciate any input.
Ever tried updating your baseband?

Yesterday I flashed the newest Samsung firmware. Voice seemed to work in the stock rom. I then flashed LOS again and the "crackling" in voice recording is back again.
I'm not sure what updating my baseband entails (and I don't know how to do it, actually).

LineageOS 17.1 microphone does not work in calls through phone dialer

Hello,
I am fairly new to this so please tell me when I miss some information and I will try to deliver as fast as possible.
I downloaded and installed this inofficial Lineageos 17.1 by ripee and joshuadoes (https://forum.xda-developers.com/t/...rofltexx-lineageos-17-1.4063781/post-84238527). It all worked and I would be VERY happy. Unfortunately though, the dialer app, even though it has access to the microphone, does not even request using it (says it has never used it). In calls, my voice is not transmitted. I still hear the voice of the other person though.
Can anyone help me? Is there a way to install another dialer app as the primary app? I tried TrueCaller with no luck. I tried rebooting, and re-installing the custom rom and testing it without anything else installed. It does not work. Calling through WhatsApp and Signal, for example, works. Also the mic is working for videos etc.
Hope you can help me out, and thanks in advance for any ideas. I really like the LineageOS 17.1 experience but not being able to do voice calls is a dealbreaker for me
I have a similar issue. however I can't hear audio during calls as well as the app not accessing the microphone. I have a Samsung A11 and I am using the a GSI LineageOS build from Andy Yan. I have tried with LineageOS 17 and 18.
