[alsa-devel] ATI Technologies Inc SBx00 Azalia

[Markus Rechberger]

Hi,

there seems to be an issue with this ATI SBx00 Azalia driver.

nmixer (which uses the oss emulated interface shows up 4 controls)
Vol (volume which seems to control the whole output volume)
PCM2 (maybe not routed on that notebook, it practically has no effect)
IGain (guess for the microphone which I haven't tested yet)
Digital1 (don't know)

if I try to start alsamixer, it doesn't seem to work and I get an
entry in dmesg whenever I try to run it:
$ alsamixer
alsamixer: function snd_mixer_load failed: Invalid argument

$ dmesg
...

maybe someone has more insight in that intel-hda driver.
