Yes it was. After at least a few sessions of Q2 :)

Apperantly not. Just to be sure, I just entered Q2 again, made some noice and
checked it again. Still 0. And it didn't help to try one of those applications
in which I have problems. Still 0.

But is it really supposed to increase? I don't know much about hardware, but
isn't the interrupts there to make it possible for the soundcard so speak to
the comp., so to speak? Isn't the DMA channel used when playing sounds, i.e.
when passing data on TO the soundcard?

Ah well, that is probably 100% incorrect...

Well first of all, as I said, it worked fine before, using the same HW, ICQ and
DMA. And secondly, my comp. is an old P133, so the BIOS doesn't have that kind
of settings yet, so I can't try chaning that. It does have PnP though, but the
MAX doesn't support it, so I guess that can't be the problem?

And btw, I am not setting the DMA/IRQ manually. It's autodetected. I just do
"modprobe snd-gusmax".

Anyway, thanks a lot!
