MIC + alsamixer no save

Hello, the alsamixer is launched and the card is reconized but no action with the level of the card ? and after a reboot the level didn’t changed ? config : rpi4 , os bullseyes lite fresh install Any idea will be very appreciated many thanks…

In alsamixer or in the Desktop of PI OS in the top-right corner, can you select the sound card?


hello yes I can do that but via via the ssh session I have :
x- (by default) ---- >pulse audio mixer
x0- snd_rpi_googlevoicechat_soundcard
The only way to act on the volume is to use the pulse audio mixer ?

another question : I need to use the sound card with a root session, If I try here"s the answer :
root@raspberrypi:/home/pi# alsamixer
XDG_RUNTIME_DIR (/run/user/1000) is not owned by us (uid 0), but by uid 1000! (This could e.g. happen if you try to connect to a non-root PulseAudio as a root user, over the native protocol. Don’t do that.)

How to run the alsamixer with the pulse mixer tab in root ?

Many thanks for your help :slight_smile:
