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. >Release-Note: >Audit-Trail: >Unformatted:
