Public bug reported:
I'm currently running Feisty on a Toshiba Satellite A100, which uses the
snd-hda-intel ALSA driver. After upgrading from 2.6.20-8-generic to
2.6.20-9-generic, the sound is an order of magnitude quieter; turning
both the hardware and software volume controls up to maximum gives a
barely-audible whisper. When viewing alsamixer, several sliders are
missing or inactive, including the "master" slider (which merely has an
on/mute switch instead of an adjustable sound level).
>From what I can see, the 2.6.20-10 upgrade still contains the broken
driver. Aside from the odd crackle when using SDL_mixer/OpenAL
applications, 2.6.20-8 had no problems handling the sound card.
** Affects: alsa-driver (Ubuntu)
Importance: Undecided
Status: Unconfirmed
