Comment 25 for bug 21804

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@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
alsactl: set_control:1389: Cannot write control '3:0:0:EMU10K1 PCM Send Volume:0' : Operation not permitted'... ...done.

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@j:~# uname -a

i hope this proves useful for someone!
