Good day, dear ALSA developers!

I've got several boards based on Intel G41 chipset, which has ICH7
south bridge with VT1708B codec on it. While VT1708B seems to be
supported since 2007, on all my computers the card is recognized, but
mixer does not work:

  $ alsamixer
  alsamixer: function snd_mixer_load failed: Invalid argument

I've tried it on Debian, OpenSuse and Ubuntu (including nightly
builds), both 32 and 64 bit version, on 4 computers (all have the same
hardware) - result is the same: card recognized, sound is played, but
mixer (volume channels, etc.) does not.

So, I've thought, that since G41 is rather new, may be this ICH7 with
VT1708B combo is not supported by alsa yet?

P.S. If you think this message rather belongs to users and not devel
list, just tell me to go there. I've just thought that supported/not
supported question should better be asked devel list.
