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.

My patch should not have changed anything regarding the ICE1724 chip
(except that the Prodigy 7.1 LT is accepted by the driver). Earlier you
were able to play audio with the card, but you had no actual sound (since
the digital-to-analogue didn't work).

Thing is also, that the ICE1724 driver only supports audio in signed
32-bit, and XMMS only plays 8-bit and 16-bit (in general, its ALSA support
is quite lousy).

The solution is to let ALSA convert the audio to the right format. This
can be done in $HOME/.asoundrc:

pcm.!default {
    type plug
    slave.pcm "hw:0,0"
}

ctl.!default {
    type hw
    card 0
}

Alternatively, you can substitute !default with !prodigy or something, and
instruct XMMS to use "prodigy" as device name.

In my opinion, the best way to test, is to use aplay ("aplay -Dprodigy
file.wav" for instance)

Also, remember to check that sound is enabled in the mixer etc.

I tried that "aplay -D nforce " the onboard produces sound and gives
message "Playing WAVE ....". "aplay -D prodigy " gives message but no
sound.  Also when I had forgotten to kill esd before hand nforce worked
the same but for the prodigy aplay got stuck before the message, but
probably that doesn't actually mean anything.

My asound,conf file:

pcm.!prodigy {
    type plug
    slave.pcm "hw:0,0"
}

ctl.!prodigy {
    type hw
    card 0
}

pcm.!nforce {
    type plug
    slave.pcm "hw:1,0"
}

ctl.!nforce {
    type hw
    card 1
}
