Anyone know if the ATI TV-Wonder support this?

I have been able to gather that it's ~32k (or is it 48000 -- there is
reference to this value in the driver) only and only capture, no
playback (that is a bummer -- I really want a second mixer for
playback).  I have recorded from /dev/dsp1:

# cat </dev/dsp1 >/tmp/dsp.out

It would be nice.  :-)

I didn't find any reference to btaudio there but did find info
elsewhere.

Do you use the driver in analog or digital mode?  I would think I
would want analog no?

I have not been able to play the resulting datastream back (through my
sound card) though.  I am trying to play at ~32k, 16bit, stereo and I
have tried all of:

Signed 16-bit Little Endian
Signed 16-bit Big Endian
Unsigned 16-bit Little Endian
Unsigned 16-bit Big Endian

and get either silence or white noise.

Any hints?
