Hardware • Upgraded from Debian 11 to 12, sound no longer working

Try going into the Configuration tab of pavucontrol and set the HDMI device to Off.
There were no devices listed on any tab. This squares with KDE's volume control reporting "No output or input devices found."
Both the devices use snd_hda_intel driver so you can't specify default using that. Did you try the second option in that wiki link?
Create a file /etc/modprobe.d/sound with this content:

Code:

options snd_hda_intel index=1,0
^This one usually works for me.
I just attempted this and restarted. Same result for the playback, the only change was the output of:

Code:

joebob@DESKTOP-300RKCR:~$ cat /proc/asound/cards  0 [C920           ]: USB-Audio - HD Pro Webcam C920                      HD Pro Webcam C920 at usb-0000:0b:00.3-4, high speed 1 [NVidia         ]: HDA-Intel - HDA NVidia                      HDA NVidia at 0xf7080000 irq 110 2 [Generic        ]: HDA-Intel - HD-Audio Generic                      HD-Audio Generic at 0xf7a00000 irq 112
Default card may also be set by pressing F6 in alsamixer which is part of alsa-utils package.
Attempted this too, but no change. I am unclear on how to ensure that the selection I made was saved after exiting, so I am unsure if that took.
