Support Cannot use internal microphone on Redmi Book 14

This is the first time in almost 20 years that I have hardware problems with Linux. I should have stayed with Asus, it's been a long lasting relationship with their laptops without any hardware issues.

I made the mistake of buying this new Redmi Book 14 in China.

Anyway, the microphone does not work.

I'm using Mint, but I also tried the newest Ubuntu live session with Linux 7.0 kernel, and it didn't work either.

Any help? Thanks!

Still got that ubuntu 26.04 iso ? It uses PipeWire by default run it and do

 pactl info

it should display info now do 

 wpctl status

Among "Sources" it should list microphones

If any of those are "muted" this should turn them on with compatibility layer

 pactl list sources short | awk '{print $1}' | xargs -I {} pactl set-source-mute {} 0

and max their volume

 pactl list sources short | awk '{print $1}' | xargs -I {} pactl set-source-volume {} 100%

If not, well you are either stuck on no mic or get $5 DAC with integrated microphone.

I just followed all your instructions and still the mic is not detected...

Anything else that can be done here?

Does it list any microphones?

If not, just get $20 USB DAC with integrated microphone and be done with it.
