Bug Description

Out of the box the sound card is not detected by ordinary users in Ubuntu 10.04 with kernel 2.6.32-24-generic 32 bit. Running 'alsamixer' returns a "Device not found" error and 'aplay -l' does not detect anything either. Running the same commands as root return information about the card. The card is detected in lspci and lshw and according to lsmod the snd-hda-intel module appears to be loaded correctly. Adding users to the audio group allows them to run alsamixer and aplay, including (supposed) playing sound, but no sound is produced. I've checked the alsamixer settings and everything seems to be okay there, i.e. nothing is muted. I've also tried installing linux-backports-modules-alsa-lucid-generic but that hasn't helped either.

Please see attached output from 'ubuntu-bug alsa-base', 'dmesg' and 'lspci -vvv'. If you need further information let me know.

I think there are two separate issues: permissions and playing sound. With my recent 12.04 beta install, I find that ALSA doesn't work out of the box for users other than root. Adding users to the 'audio' group solves the problem. (I don't want to run pulseaudio, since it depends on too much gnome stuff, which I try to avoid).

Does your sound work with the Precise/12.04 LiveCD/USB? If so, then the issue you're describing is due to your removal of pulseaudio.
