Creative Labs SoundBlaster 128 PCI Hangs

Hello!

I've just recently joined linux-sound, and have been "lurking" up
until now.

I have a Creative Labs SoundBlaster 128 PCI. It dosn't work. It
will begin playing a wav file, but an indeterminite time later (10-40 seconds), it hangs the system. The only recovery is a reset. When it hangs, there is a high pitched tone, about 20% volume, that sounds like a square wave to me.

I've read everything I can get my hands on, and have only one clue
so far: in .../drivers/sound/es1371.c, there is a comment about adding code to handle Rev 7 boards. My board reports itself as Rev 8. Curious, no?

The Sound-HOWTO mentions this very behavior, playing awhile, then
hanging, perhaps with a never-ending tone. The cause is an IRQ or DMA conflict. Since this is the PCI bus, I don't think this is the problem.

Can someone point me in further possible directions? I'd be
willing to try most anything.

Thanks!
