thanks!  applied now to cvs.

actually there are no ALSA controls defined for hoontech's DAC/ADC.
the (most of) cards from m-audio and terratec have analog controls.
it depends on the card design, of course, though.

sorry, no idea about this box.

hmm, i also don't see the reason why not work.
hoontech's gpio_write is it's independent from other cards'
routines...

it's impossible on the kernel emulation route.
you may try the alsa-oss emulation library.

in theory, it should be accessible normally as mixer controls
(i.e. via alsamixer).
but the ac97 controls look not working well atm.
