[linux-audio-user] simple usb audio question?

[Dylan McNerney]

This is probably a very basic question, because all references to usb
audio seem to relate to quality, rather that getting the device working,
but I'm new to linux.  Currently I can't capture from or play to my
Edirol UA-25.  I assume it is in conflict with the onboard soundcard
which is an nForce3, but don't know which modules to remove, etc. I
tried taking out the snd_intel8x0 driver, but then mixers didn't find
anything at all.  The device seems to be recognized in the sense that
the Suse control center sees it as a midi controller, and I tried to add
it as a generic usb audio in YAST, which seems to have put it at hw [1].
I followed the ALSA project instructions for the modules.conf file
and .asoundrc but not sure what I should be looking for now.

I'm running Suse 9.2 x86_64 with custom 2.6.11.12 kernel with
realtime_lsm module.  The device works fine in windows.

Thanks for any help.
