Below is a patch to fully enable the Hoontech ST Audio DSP24
Media 7.1.  It appears that this card is supported.  It was nice
to see all the output controls in envy24control.

Some quick questions. 

1) After reading old posts in the mailing lists it appears that
the hoontech ice1712 cards don't have the option to change the
input gain (analog volume) on analog input. I see no analog
volume controls with amixer, or envy24control. Is this true? What
ice1712 cards have analog input volume/gain control?

2) Does anyone know the correct way to set the spdif for
consumer/professional mode on this card? 

3) Claus at st audio support said that this card would not work
if gpio_write calls in hoontech.c were made to initilize the box.
However, I see no difference using these calls or not using these
calls. Does anyone know for sure? Claus said that someone on the
mailing list would know the answer.

4) How does one turn off the extra output channels when using oss
supported applications, or use only certain output channels when
using oss supported applications?

5) How does one access/use the ac97 part of this card?

6) Comments on the card/external box. The RIAA phono pre-amp
sucks big time. Does not even compare with a cheap phono pre-amp.
Can't record at 96000Hz without overruns using low latency patch
and every service I could disable. Card has it's own IRQ also.
May have something to do with the via KT133 based motherboard I
have. 

Thanks 

Henry

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.


ciao,
