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.

You are correct about only needing to compile the ice1724 driver.

Up until I started having problems with sound, I have just been using
modules that were already built as part of the Fedora Core 3 distribution
(or updates to it).

Now I am going to just go straight to the source and compile my own
module, using the patches here; and start experimenting with that.

Looking at the list of components:
1. WM8770IFT  --> this is the audio CODEC
2. 3CZ09FJ  --> unknown right now, someone else mentioned a Texas logo, so
probaby a TI part--I used to work for TI, but so far I haven't found this
in their product list, I'm guessing it is a buffer, probably similar to
chip https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3; or maybe it is
the S/PDIF transcoder.
3. HC125A, PAU139 --> buffer IC, commodity part available from TI,
Motorola, ON, etc.
4. IL1117-33, 451 --> low-dropout voltage regulator--power conditioning
for the chip
5. ATMEL426, 24C02N --> 256x8 EEPROM
6. H17A, 316BJ --> from the photo and part number, I'd guess a transistor
or diode
7. NCO-3.3V, 49.152MHz, NTE --> oscillator that probably sources the
codec

I will look at my card tonight, but it does appear that they are using 6
amps (makes sense, 6 amplified channels).  The parts in the diagram marked
"voltage regulator?" are definitely voltage regulators.  Looks like one
resistor pack a little close to one, but not too bad.

I will focus on looking at the amps, figuring out how they are controlled,
where the gain setting comes from, etc.  Basically how it is supposed to
work.  Once I understand that, it shouldn't take long to figure out how to
command it to do what we want.  I found the datasheet to the CODEC here:
http://www.profusionplc.com/static/images/data%20sheets/wm8770ift.pdf

Looks like it has its own amps with builtin digital pots, so this is where
all the volume control is really being done.  If those other chips are
amps, then they probably just have a constant gain on them...maybe they
are with unity gain and just isolating signals--dunno at the moment.  SPI
is probably being used to control this--the chip supports an SPI or CCB
(Sanyo-specific 3-wire bus) control bus.  From what I can tell on the
Envy24 family (ice chip) it looks like a codec that supported a I2C
control bus would've been easier.  Maybe they do control by bit-banging
some GPIOs, since there are plenty of them around?

Interesting.  I'll let you know as soon as I have something.

It was I who reported the Texas logo but my number was 3AZ6D5J not the
number reported by baesyspem.
