Comment 30 for bug 195605

Hi Michael,

It seems one of upgrades removed these lines. Yesterday I made update and
put absent lines
options snd-card-0 index=0
options snd-hda-intel model=vaio
alias snd-card-0 snd-hda-intel
to alsa-base.conf and got sound after reboot of the computer. Resetting
alsa driver without reboot
( sudo /etc/init.d/alsa-utils restart ) did not helped.

Thanks.
