Comment 15 for bug 93859

I had extremely low/absent sound on my Toshiba A105-S4134.
Upgrading the alsa drivers to the most recent version made the sound work some of the time.

however, adding 'options snd-hda-intel model=auto' to my /etc/modprobe.d/alsa-base made the sound work perfectly.

Thanks a million for the workaround! The changelogs for the latest alsa drivers (1.0.14rc4) mention fixing compatibility issues with Toshiba A100s, so it seems like they are working on it...
