I just upgraded from 10.04 and lost sound.
aplay -l gives me
while lspci -v gives
aplay: device_list:235: no soundcards found...
find /lib/modules/`uname -r` | grep snd
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)
Subsystem: ASUSTeK Computer Inc. P5B
Flags: bus master, fast devsel, latency 0, IRQ 3
Memory at febf8000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel modules: snd-hda-intel
gives a whole lot of stuff, which I assume means I have the sound modules installed.
The soundcard worked just fine before the upgrade, so I assume this is a some kind of a configuration problem. Any help on this?
Now this is embarrassing.
sudo modprobe snd-hda-intel
did the trick.
