Works great with linux. Latest Alsa driver (1.0.3) works perfectly and is recommended over the OSS kernel driver. Optical inputs/outputs works too.

Must add module option mmap_valid=1 to your modules.conf (or modprobe.conf) for the snd-cs46xx module to get sound support in Quake3 based games.

Works fantastic with the RCA outputs on my GTXP. havent tried any of the optical ports yet though. ALSA 0.9.6 (found on slackware 9.1) had no problems finding drivers for it.

Chip = Cirros Logic C54294 rev 5.

Based on the CS4630 soundchip and provides excellent reproduction in RCA/jack or optical/cable SPDIF output.

ALSA version 1.0.5 with module snd-card-cs46xx works very nicely.

Breakout box is a bit clunky and often one of the solder joints on the headphone output gives way (any easy fix) but it does save crawling around the back of teh box to plug things in.

Make very sure that you install with the right kernel link otherwise you may get odd results. Use ./configure --with-kernel=/usr/src/linux-x.x.x to force the issue.

I figured out that many people get the Game theatre XP 5.1 and 6.1 to work. I have a 7.1 and I begin to wonder if there is something about this card that differs from the others.

To begin I can say that this card works under kernel 2.4.29 and it works good. Although, and this is funny, the card is identified as a CS4294 chip but it can be used using the kernel drivers for CS46xx.
In kernel 2.6.11 I have great difficulties making the card work. I installed Alsa-drivers 1.0.8 and it finds my CS46xx (CS4294?) using alsaconf and sets my modprobe file but when I run cat /proc/asound/cards the card just wont show up. I dont know how to make it work with this kernel, even if I choose the CS46xx alsa-drivers in kernel it wont work.

I have heard of people getting it to work with the 2.6.10 kernel.
