Hello,

I know this is impossible but this list is my last resort. IF it doesn't
work i have another laptop that works out of the box but i really like this
laptop (Chromebook Hp x360 14c)

Everything works except sound that does work when connected to HDMI. Here
is what I have to work with.

Sndstat

cat /dev/sndstat

Here is a thread with the exact same issue that didn't get resolved

https://forums.freebsd.org/threads/no-sound-with-sound-card-intel-comet-lake-pch-lp-cavs.87085/

Like I said it's probably impossible but I'm ready for that. I was
advised here that since there are no other nids or pcm's that they
can't do anything

Thanks for looking at it
