Yesterday, I switched from nVidia driver 515 to 525 and shutdown my PC later. After I booted this morning, the driver changed from 525 to X Server and caused some graphics issues, I managed to solve by switching to nVidia again.
Now the actual problem: after switching to the nVidia-driver-525 again, I have no sound. The output option in sound options only show "Dummy Output", but no actual sound device.
When I run aplay --list-devices, it returns this:
aplay: device_list:274: no sound cards detected
pacmd works fine. lspci returns this:
