Hi!
Installing PureOS on my Dell Latitude 3510, cannot use sound card. Webcam works fine and I get drivers for the wifi card https://packages.debian.org/bullseye/firmware-atheros.
So, my sound card seems to be: comet lake pchlp cavs (at least, this is what appears when I ran one live version of Linux which detected all the hardware in the system).
Thanks for help!
