    I have an ISA soundblaster on the motherboard, and a CDROM on an
    ISA controller. If I try to access the CDROM while playing sounds,
    like playing an MP3 off the CDROM, or burning a CD while listening
    to realaudio, I get skips. Absolutely no skips if I'm not using
    the CDROM. Kernel is 2.2.10.
