This may be related to 'extra features and configurability', see below, maybe
you should use another plugin or configure it differently?

Interesting problem, is this the emergence of Artificial Inteligence ;)

How about disabling it once in the BIOS for testing if it's indeed an IRQ
problem? I think it may be related to a soundserver you're running: artsd in
KDE or esd in Gnome.

On my Asus P5A mainboard I can assign IRQ's for PCI slots in the BIOS, if you
don't have that option try moving the soundcard to a different PCI slot.

You have an 'advanced' soundcard and are using the ALSA 0.9beta drivers.
ALSA 0.9.x is part of the recent Linux 2.5.x development kernels :) Your card
and the advanced drivers you are using result in extra features and
configurability which is documented of course, I mean people are succesfully
working on the documentation, but it's far from complete, help appreciated...
Btw, there are more recent ALSA beta drivers.
