[alsa-devel] Random controls with hda-intel

Hi guys,

This is a problem I already posted on alsa-users, but since the only
reply I got was a me-too, I'm posting here.

I have some problems with the snd-hda-intel driver. The mixer controls
seem to be unpredictably appearing and disappearing or changing type
(on/off-switch vs volume) from alsa-driver
version to version. In the current daily snapshot (12th Sept 2008) I
have no volume control at all. In the driver shipped with 2.6.25 kernel
at least I get a pcm volume control. Several driver versions ago (dont
remember the version number) I had a master volume control. Several
other controls seem to have no effect on anything.

When loading the snd-hda-intel driver, I get in my syslog:

 hda_codec: Unknown model for ALC861, trying auto-probe from BIOS...

The alsa info script has uploaded my infos here:

Any help is appreciated
