Ok, here small additions:
es1968 (maestro2)
up to 4 channels as default, more configurable by module option
maestro3
up to 2 channels (so far due to lack of h/w info)
ali5451
basically compatible with trident (on OSS it's the same driver)

IMO more specific (detailed) information for each card should be
included in alsa-driver distribution..

IIRC, esddsp emulations only OSS not ALSA.
(same with artsdsp for artsd).
Hmm, do we need ALSA "arts" and "esd" pcm interface..?
