Public bug reported:
After booting the sound icon in notifications area looks like sound is
muted. When opening mixer application it shows that it is not muted but
it does not show any audio devices in "Hardware". Sound does not work.
Kernel seems to load modules and recognize audio device, but lspci shows
"access denied" on "Capabilities":
x...@xxxxx:~$ lspci -v | less
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
Subsystem: Hewlett-Packard Company Device 30c2
Flags: bus master, slow devsel, latency 64, IRQ 16
Memory at 84000000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel
Alsa Information Script 0.4.59 shows:
/sbin/alsactl: save_state:1502: No soundcards found...
This does not happen on every boot! Sometimes it does work properly.
Issue came up after installing Lucid Lynx. It always worked on Karmic.
Please tell me if you need any more information on this issue.
