I first noticed something was wrong when I installed the latest Clementine update earlier today. The tray icon for it did not appear so I restarted the application, then the whole application would not start, then I noticed sound was broken entirely, so I rebooted the system figured it'd been three weeks and I probably needed to anyway. I actually ended up rebooting several times after this due to an unrelated issue with X (that turned out to be my own fault) but audio has not returned. I'm thinking the issue with Clementine is probably unrelated since I've not even tried to start it after my latest reboot and audio is still broken, but I felt I should mention it.
Edit: After a bit more troubleshooting I think the problem is with PulseAudio but I'm still not sure.
The results of cat /proc/asound/cards:
- Code: Select all
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xfb430000 irq 50
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfb080000 irq 51
Somewhat promising as it lists both HDA Intel and HDA Nvidia. The results of cat /proc/asound/modules:
- Code: Select all
0 snd_hda_intel
1 snd_hda_intel
Only lists HDA Intel. Most curiously, the results of aplay -l:
- Code: Select all

Seems fairly obvious that ALSA is working and can see the ALC892. However doing aplay /usr/share/sounds/alsa/Noise.wav as root results in silence. I tried messing with the --device setting in vain, I get either an error (aplay: main:828: audio open error: Device or resource busy) or silence.
Also alsamixer lists both card and chip as PulseAudio and just Master volume, which is set to 100.
