Here's the output of dmesg concerning my sound card:
ATI Technologies product 0x4341 (audio multimedia) at pci0 dev 20 function 5
not configured

So each time an application needs to access /dev/audio I have
to figure out how to configure it to use a null driver instead
(for instance ogle crashes if I don't do it).

I'd like to find a way  to attach /dev/audio to some sort of null
driver such that each application which needs /dev/audio don't complain.
Also, it seems to me that this trick would give me less work
if and when there is support for my sound card.

Thierry.
