I had my soundblaster in the kernel at IRQ 10. When I tried out OSS, it reported a conflict getting IRQ 10 which stumped me for a long time, then I realized that rndcontrol was grabbing IRQ 10 for use by /dev/random before the sound driver could get it. My problem now is anything that tries to write to /dev/dsp becomes unkillable, and (according to top) the kernel continuously pages out at about 700K/s until I reboot. Top also reports the cache size to grow to about 15 megabytes (32 megabyte machine). Bizarre. Anyway, I don't really have the spare time right now to fiddle so I've gone back to the stock sound driver. -john
