>Description:
	During heavy I/O, sound playback slows to approximately 0.5X-0.8X
	original speed. This has been reported by many users with hardware
	of various capabilities, from original Pentiums to Dual Athlon XP
	systems, and appears to be independant of sound hardware as well.
	It is also independant of the I/O system in use, as both SCSI and 
	ATA disk/optical devices will cause this to happen.
>How-To-Repeat:
	Play your favourite song with your favourite audio player, while
	burning a CD, unzipping an archive, or anything that will cause
	heavy I/O.
>Fix:

	Some people can get away by disabling daemons like esound, others
	are not so lucky. Many have guessed that it is a problem with 
	interrupts in the kernel.
