Dell XPS 17 (9710) Internal mic doesn't work

Kernel 5.15.0-rc4-next-20211011-1-next-git
Sound works fine except for microphone - I've gone through the diagnostics procedures described in the wiki, still have no idea what's wrong.

$ arecord -l

card 0: sofsoundwire [sof-soundwire], device 4: Microphone (*) []
  Subdevices: 1/1

$ cat /proc/asound/modules                                                   
 0 snd_soc_sof_sdw

$ lspci -v | grep -A7 -i "audio"

I'm new to Arch, so any advice on how to find out what's wrong/fix it is very welcome. Thanks in advance!

I had also microphone issues, which got fixed by the discussion here: https://github.com/thesofproject/linux/ … -919171839

You can try to do the same I did which made it magically working for the mic

execute

alsamixer -Dhw:1

play with the rt715 (just move them up and down)

exit and reboot

now execute again

alsamixer -Dhw:1

This procedure for some reason made new rt715 switches appear for me which allowed me to make the mic workable.

And btw. alsamixer is included in alsa-utils I think shouldn't  you have it installed yet.
