I have an Asus P5SP4 board with a P60 and 16 Mb DRAM, and an SB16 2230 with ASP. Uder DOS and Linux the sound card works fine (0x220, 0x330, 0x388, IRQ 5, DMA 1 & 5), but under Win95 (same io) sound is crackling a lot, also when I run DIAGNOSE from a DOS window. I upgraded to an AWE64 gold, installed all the new software, but the crackling is exactly the same. I could not find a conflict; the only strange thing is that in the IO resources windows it says 'used by an unknown device' for ~all~ addresses, apart from the allocations you expect. The crackling occurs even if I remove all my other cards (apart from PCI VGA card). Any suggestions?
