Sounds like you're trying to play back HDTV recordings with a 32kHz AC-3
track and you have AC-3 passthrough enabled. That will not work with
nearly all PC sound cards available (they tend to only work with 48kHz
AC-3--and before you say, "It works in Windows," I'll say that Windows
drivers tend to recode the 32kHz AC-3 to 48kHz AC-3 before "passing"
through).
