Whenever you get white noise, it's pretty likely that there's an endian
problem in one of the programs involved. The low 8 bits of a 16 bit stream
usually have a fairly random (white noise) distribution, so if they're
getting treated as the high bits, you hear noise.
I read that newer Macs can't play audio CDs normally, by design. They read
the digital data and feed it to the sound card. (this is what the audio cd
reader should do, I think). Most CD-ROM drives have a digital out as well
as an analog out, I don't know why they didn't just connect the digital out
to the sound card, instead of wasting CPU time doing it.
