Title:
PCI/internal sound card (chtnau8824) not detected updating from
5.11.0-27-generic to kernel 5.13.0-27-generic (Dummy output)
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
I was running Ubuntu 20.04 flawlessly, but when I got an update from the
kernel 5.11 to the 5.13, then I got the dummy output and no sound comes out
from my speakers or mic.
I made a fresh install without updating and I got the sound back. When I
update the issue comes back.
The same problem occurs in other distros with the 5.13 kernel and with the
5.15 as well.
I've seen occur in Pop!_OS both 20.04 and 21.10 and in Ubuntu 21.10 with the
related kernels. No troubleshooting fixed the issue.
When my sound was working the name of my audio device was chtnau8824.
I tried inxi -A and got this output:
