I don't have any idea at this point. Historically that kind of noise was an IRQ or DMA conflict but from your description I don't think you have one at this point. One of the problems with PNP is that it can grab a hardwired spot and cause problems. That is why people have called in Plug N Pray for years. Windows has started doing a better job of handling combinations of PNP and legacy devices. If you remove or simply move a card, you can still have problems with Win 9x. As far as the sound card drivers go, I have only used pcm and haven't noticed any problems. I had to add sbc0 for the oldest ISA SB card but that is all covered in the documentation. The newer SB and the Ensoniq ES-1371 that Creative markets only required adding "device pcm" to the kernel. You had to MAKEDEV snd0 in /dev to finish the job in all cases but that was basically it. I don't have anything hooked up to the joystick or play with midi and etc., which makes my setup really simple.
