Unrecognized AC97 codec

I have a new board with ESS Canyon3D-2LE (Lite) chip, which apparently
has integrated AC97 codec. The codec is not recognized by ac97.so and
reported as ‘Generic AC97 0x45838300’. I suspect the vendor of codec is
also ESS, since they do have their own AC97 codec.

It mostly works, with following exceptions:

  • AUX and VIDEO outputs are not supported (they are considered optional
    now, in latest Intel specs);
  • STEREO_MIX input does not appear to work, but selecting either AUX or
    VIDEO appears to have the effect which STEREO_MIX is supposed to have.

The chip is supported by my Maestro-3/Allegro driver.
