Hi.
I've got a bit of a odd situation. I can listen to music through
my Soundblaster 16 perfectly, and copy files off a CD-RW perfectly,
but problems occur when I do both. Specifically, the sound from the
sound card almost "slows down". The minute I cancel the reads from the
CD-RW, it's perfect again. The Soundblaster is a recent addition.
I've looked for obvious things like same IRQ or DRQ, but can't find anything.
Does anyone have any ideas ?
The sound card claims to be set to IRQ 10, using DMA 3 and 7, and
using IO address 220F. The SCSI card claims to be using IRQ 11,
using DMA 6 and IO address 330H. From what I remember,
there might be a problem with the Soundblaster using 330H as well.
/dev/sndstat says

Installed devices:
pcm0: <SoundBlaster 16 4.13> at 0x220 irq 10 dma 7:3
which I believe precludes the Soundblaster using 330H at the same
time as the SCSI card.
