I'm using 12.10 Quantal with Openbox and a .xinitrc script at login instead of a display manager.

It's a relatively fresh install and I noticed when I opened pavucontrol the only output was a dummy one. I checked around and it appears that my sound card is physically installed but Pulseaudio isn't detecting it. I'm really unsure of what I should do but any help getting my audio back would be appreciated.

Edit: further info if its at all useful:

Seems like ALSA does not recognize your soundcard. You may get additional information on drivers loaded/needed with hwinfo --sound . – Takkat Oct 18 '12 at 19:37

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

Possibly something is monopolising the sound devices. Try

sudo fuser -v /dev/snd/*

on command line to see what takes the sound devices and stop it. Then try again.

Had same problem. GDM was the 'user' controlling audio. Sollution here: http://www.debuntu.org/how-disable-pulseaudio-and-sound-gdm
