[Pkg-alsa-devel] Bug#290793: alsa-base: ALSA fails to work on via VT8233/A/8235/8237

[Jonathan Lucas]

Package: alsa-base
Version: 1.0.7-2
Severity: important

For about two months or so, my sound setup has failed to work with
ALSA. I've thought for a while that the problem was my motherboard, but
a bit of experimentation today revealed that it works on OSS. Possibly
related (possibly not, who knows!)  information is 

a) Turning up the microphone volume causes various noises to come from
the speakers, ranging from clicks to continuous tones.
b) From memory, when it last worked, on the mixed settings, I had a
slider for the PCM output. Now I only have a checkbox.

For background, output of lspci for my PC is as follows:
