It shows both of my Delta 1010s and the on-board C-Media card. One of the Delta cards and the C-Media card are sharing IRQ 5, and the C-Media card is the default sound card. I don't understand this, because I have disabled the C-Media card in the BIOS.

xmms -> Options -> Preferences -> Audio I/O Plugins/Output Plugin/Configure

I got yours - thanks. Mine looked the same, but I could not resolve the issues I had on Ubuntu, so I switched to a bare-bones Debian install, only adding packages I needed from etch. Along the way I discovered part of the solution - I modified /etc/modprobe.d/alsa-base, adding "options snd-cmipci index=2" to the end of the file. This prevents the C-Media card from being the default sound card. That, and running "modprobe snd-seq" pretty much solved my problems, and I am even getting lower latency numbers than with Demudi. Thanks for your help.

I know - I have been using two on my Windows mobile DAW for almost 2 years - I'm just trying to transition them over to Linux.
