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. ====================================================================== ---------------------------------------------------------------------- ungod - 05-10-05 09:36 ---------------------------------------------------------------------- Well, I suppose reverse engineering is the solution. Which reminds me that Audiotrak have seperat drivers for Prodigy 7.1 and Prodigy 7.1 LT, which indicates that they aren't that much alike. According to Audiotrak there is no AC97 chip onboard, which means two chips lesser, and 12 additional free GPIO pins on the ICE1724 chip. Said in a other way; AudioTrak probably haven't used the same GPIO pins on the LT model as on the ordinary Prodigy. It looks like there is an AC97 chip on photos though. Unfortunately there is no safe way to figure out the behavior of the GPIO pins in software. The best thing would be to look at the board and optionally use a voltmeter to figure out where which GPIO pin goes. Speaking of which, the External Amplifier is located on the last stereo output (channel 7 and 8) instead of front as on the Aureon and Prodigy 7.1 card. ---------------------------------------------------------------------- Demosthenes - 05-10-05 15:50 ---------------------------------------------------------------------- Is it possible I can do this (look at the board, maybe use voltmeter) without knowing anything about GPIO pins, if someone could instruct me as to what to do.
