I belived that it use DMA so the soundcard should have enough samples in DMA buffer to play for a while during disk access...

Maybe USB emulation BIOS routines are too slow that DMA buffer underrun? I cannot belive it could take such long time... (I have USB legacy support disabled and still use PS/2 mouse and KBD so no need for it).
