Florian,

Yes, I see amixer must be used. The proble is, hdsp driver maps card's mixer
controls to alsa mixer controls in not-obvious way.There was somewhere some
information about accessing hdsp mixer controls (how to relate channels and
appropriate controls, write (and read?) values and such), but I can not found
it now (probably it was at old alsa site).

The card has

numid=5,iface=HWDEP,name='Mixer'

control, and, probably, something like

amixer cset numid=5 x,y,z

must be used. What are those x, y, z? :-)

OTOH, it seems like I can not get current hdsp mixer settings: 'amixer cget
numid=5' just returns a tuple with three zero rather full 3dim matrix. Can I?

Has anybody elaborated information about all these issues?

Andrew
