I've been using the Audigy 2 Platinum EX for a couple of months now. (It's even happily coexisting with a second (run-of-the-mill) sound card I have installed in my Red Hat box... bonus! :-) I'm using the emu10k drivers at http://sourceforge.net/projects/emu10k1/ . I'm not sure that all of the Audigy's features are supported, but since I only care about stereo in and out that's OK for me. The Audigy has a gazillion inputs and outputs (at least it seems like it); the toughest part is figuring out how to use emu10k's support program to patch these ports to OSS's ins and outs...

As far as I can tell with the way I have things set up, the highest sample rate in and out with GNU Radio is 48 kHz. Since the card supposedly samples inputs at rates up to 96 kHz and playback at rates up to 192 kHz, I need to figure out if it's my installation or the linux implementation that's the limiting factor. I haven't dug that deep into it since I haven't needed the higher sampling rates yet, but I plan to...

Does anyone else use this card with GnuRadio, or
know if a suitable driver exists for Red-Hat Linux?
