Hi. Ever since i bought my redmi 3 pro i have a microphone problem. It's not ROM related as i had it on global rom and on every xiaomi eu release up to 6.12.1.

When i call someone or get a call after a few seconds nobody can here me. Searching the web it seems to be caused by a bug in noise canceling. I couldn't find a software fix that works yet and the only workaround is to put a finger on the top microphone (next to the IR blaster).
Does anyone have a solution for this issue?
greetz and thank you.

Hey,
I have exactly the same issue. I thought it was due to hardware, but since you got the same problem it will be software probably.
Anyone got the solution? I can't find any for the Redmi 3 on the internet....

Hi everyone,
Try to add this parameters into end of the build.prop:

ro.qc.sdk.audio.ssr=false
ro.qc.sdk.audio.fluencetype=fluence
persist.audio.fluence.mode=endfire
persist.audio.handset.mic=digital
persist.audio.voice.clarity=ON
persist.audio.handset_rx_type=DEFAULT
persist.audio.fluence.voicecall=true
persist.audio.fluence.voicerec=false
persist.audio.fluence.speaker=false
persist.audio.fluence.audiorec=false
persist.audio.fluence.spk.mono=true

If you will still have a negative result after that, then try to disable the noise canceller and dual mic configuration:

ro.qc.sdk.audio.ssr=false
ro.qc.sdk.audio.fluencetype=none
persist.audio.fluence.mode=false
persist.audio.handset.mic=analog
#
persist.audio.voice.clarity=ON
persist.audio.handset_rx_type=DEFAULT
persist.audio.fluence.voicecall=false
persist.audio.fluence.voicerec=false
persist.audio.fluence.speaker=false
persist.audio.fluence.audiorec=false
persist.audio.fluence.spk.mono=false

Hi guys,
I come back to you again with 100% working solution regarding this issue. In additional to this, it resolved my issue with not working microphone on my wired headset Panasonic RP-HJX6M.
Just find and comment out the next rows in the build.prop:

#persist.audio.fluence.voicecall=true
#persist.audio.fluence.voicerec=true
#persist.audio.fluence.speaker=true
#persist.audio.fluence.audiorec=false
#persist.audio.fluence.spk.mono=true

Add the next rows at the end of the build.prop:

persist.audio.fluence.mode=endfire
persist.audio.handset.mic=digital
persist.audio.voicecall.mic=0
persist.audio.voice.clarity=none
persist.audio.aanc.enable=false
persist.audio.handset_rx_type=DEFAULT
persist.audio.nsenabled=ON
persist.speaker.prot.enable=false
persist.audio.spkcall_2mic=OFF

I have tested it on global developer ROM MIUI8 6.11.3. Besides that, the voice call has become much clearer than ever before.

for me with the fix it works for about 1 minute but if a call takes longer the sound drops again so the others cant hear me as before.

I got the same problem with different ROMS, I have tried factory reset and flashing but the same problem continues.

Tried to find and comment the rows in the "build.prop" but I couldn't because my cellphone isn't rooted...

does anyone know if there are any other solutions?

Thanks.

For me the only working solution is to cover the top microphone with a finger as i wrote in the entry post.
i wonder if its possible to just disable the noise canceling mic through the build prop.
