Chris, thanks for this tip.
It seems a very reasonable hypothesis.
One question: how do I recognise OSS modules?
Did you see any in my lsmod output?
BTW I had installed discover just tonight, to see if it would help;
obviously I'm better of without it if I want to use ALSA.
I also use hotplug, which gives me lots of error messages but seems
to work with USB anyway. It says PCI events are not synthesised, so I guess
I do not really have to worry about hotplug for the sound card?
On a related note, isn't it time for the discover program to start
installing ALSA over OSS? Or does Debian use ALSA as a default only for
the 2.6 kernel?
Thanks
John
