Not MPXplay bug but USB vs. CTmouse problem (Announce)

It's normal that on PCI bus devices cannot talk parallel to CPU but it has buffers to overcome it and continue to stram data from/to buffer even if not handled by CPU... It's seems to be some specific BIOS issue, I don't experienced such problem on my DOS machines. Maybe it could help to move soundcard to a different PCI slot (it not onboard) to change some IRQ routing...
