Recently, my AGP graphics card (Matrox G200) stopped working (a hardware defect), so I used a rather old PCI Mach64 card instead. I also have a Soundblaster AWE 64 (ISA, using pcm) in my box. Now, whenever the PCI bus is accessed while the soundcard plays something (e.g. by moving windows around or playing a movie), I can actually *hear* the bus accesses in my loudspeakers (very short and frequent pauses and clicking noises - several per second, which sounds rather strange). It was the same (but the noises where extremely rare) when my MGA 200 was still working, but with the PCI card, it is really horrible. When using Win98, my system behaves normally (no strange noises can be heard on graphics access). I figure this being a driver problem. What can I do about that? Are there any parameters I may have forgotten to set? Any help is appreciated!
