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?
