[Bug 21804] Re: alsa-utils cannot always restore mixer settings correctly across upgrades

[Jan Braunisch]

I'm running kubuntu karmic and sound worked well until one reboot (i
dont know if i had installed a new kernel before rebooting) when kmix
and amarok said the sound card is not present and not working (i
remember seeing both not present and not working)

root at j:~# /etc/init.d/alsa-utils restart
 * Shutting down ALSA...                                                                                                                                                                      [ OK ]
 * Setting up ALSA...                                                                                                                                                                                 * warning: 'alsactl restore' failed with error message 'alsactl: set_control:1389: Cannot write control '3:0:0:EMU10K1 PCM Send Routing:0' : Operation not permitted

i tried removing /var/lib/alsa/asound.state but it didn't make anything
better

lspci shows:
00:0d.0 Multimedia audio controller: Creative Labs SB Audigy (rev 04)

it's an Audigy2, i wonder why it doesn't say

root at j:~# uname -a
Linux j 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:02:15 UTC 2009 x86_64 GNU/Linux


root at j:~# rm /var/lib/alsa/asound.state
root at j:~# alsactl restore

i hope this proves useful for someone!
