Hmmm... I couldn't find anything called "Triton" on the Gigabyte site.
Is the GA-7VAXP the motherboard you're talking about? :P

My motherboard's got the same sound chip as the GA-7VAXP - the RealTek
ALC650. I do have 4 channel (front + rear) output in Windows, using the
utility that comes with the motherboard drivers. I've also got it
running fine in Linux, using the Alsa drivers, however, I only have
stereo output from it (i.e. only 2 channels thru the Line Out connector,
nothing thru the 'Line In' connector that's meant to turn into the rear
output).

Last time I checked, the drivers for the chip on Realtek's site was
simply Alsa code, so I just went with the 'official' Alsa drivers, which
don't seem to support the 4 channel output feature. I also tried the
kernel's Intel ICH driver, which actually seemed to recognise that the
chip was capable of outputting more than 2 channels (said so in syslog),
but still only used 2 channels. I later discovered that XMMS was dying
while playing WAV files with the ICH driver, so I went back to the Alsa
drivers...

I guess you could try Realtek's drivers - get them from the Realtek site
(http://www.realtek.com.tw/downloads/dlac97-2.aspx?lineid=5&famid=12&series=8&Software=True)
Those drivers are said to have been updated about 5 days ago, so I
dunno, *maybe* Realtek tweaked them to support more than 2 channels.
Other than that, if anyone else out there on the list knows how to get
Alsa (or the ICH driver) to output more than 2 channels, then please
tell us how. :)

Cheers
