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.

Yes! Lets make som support for this card!

I did some googleing for some techincal information about the Prodigy LT
model, however I didn't end up with any certain facts about the card or
highres photos.
http://www.pcwelt.de/imgserver/bdb/36500/36530/original.jpg was the best I
could find, but it is not sufficient to identify the chips, so you will
have to do that for me.

I have made a diagram (http://linux.developers.dk/prodigy.png) of how the
card seems to be organized. The red boxes are chips which may be
important. If you could write down the manufacturer and model of each of
these, things may become easier.
Chip no. 7 doesn't look like a sound-related chip, but it might be a good
idear to also write down the name of this one.

Besides there seems to be a lot of what looks like opamps (makes sense,
since this is an audio card) and a few voltage regulators, but they are
irrelevant for a driver implementation.

Just for the sport of it, I did a similar diagram of my own card (Aureon
Space 7.1). It is located at http://linux.developers.dk/aureon.png (An
actual photo can be seen at
