Title:
no sound via speakers or headphone port on Carbon X1 6th
Status in alsa-lib package in Ubuntu:
Confirmed
Status in linux package in Ubuntu:
Incomplete
Bug description:
I recently upgraded from 18.04 to 20.04. The sound worked without
problems before upgrade, but now I don'get any sound at all from the
speakers or the headphone jack.
This seems similar to
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1860697 (although
that bug is reported as resolved). I tried adding model=generic
dmic_detect=0 to my alsa-base.conf, as reported in that ticket, but it
did not help.
