Summary: Support for new Prodigy 7.1 LT
Description:
Could you please try to add support for the Audiotrak Prodigy 7.1 LT, as
far as I am aware this card is essentially the same as the Produgy 7.1 but
low profile and with a couple of physical changes such as no digital in.

ALSA does not detect the card currently and when I try to load the
snd-1724 module it fails with an EEPROM error.

I have tried compiling a new kernel with the subdevice id for the Prodigy
7.1 in aureon.h changed to correspond to my device (as detailed here for
another card
http://linux.derkeiler.com/Newsgroups/comp.os.linux.hardware/2004-10/0340.html).
Alsa then detects the card and I can load modules and change volumes in
alsamixer but I haven't been able to produce any sound.

Hopefully support will be easy to add as this card is almost exactly the
same as the Prodigy 7.1 (and Aureon Space etc.) which already have
support.

I would be very happy to give any further information needed.

As I mentioned ealier, the ICE1724 driver must get audio in signed 32-bit
format. Therefore ALSA must change the audio format on the fly. This is
done by the plug module (type plug). If you don't use the plug module, and
attempt to play ordinary 32-bit audio, it will fail.

I know that the ICE1724 stuff work, because I saw ealier that the peak
meter (Multi Track Peak) is altered when you attempt to play something.

The only thing which doesn't work, is the WM8770, which is responsible for
digital-to-analogue and analogue-to-digital conversion and attenuation.

Actually, I made a VU meter for the card once, if I can find it again (or
rewrite it), you would see it move when you try to play audio.

Right, thanks. I have tried some combinations, but not by any means all
(that would take a long time). 11 does look to be the logical place, but
alas no sound, I don't know if baesyspem tested 11 since it wasn't
highlighted on your diagram. baesyspem doesn't seem to be around at the
moment, I think I shall probably try and get at my card again and check
those pins maybe.
