In the general setup menu there are settings for enabling AC3 and DTS
pass-through over the SPDIF port.  Generally, music will be unaffected
by this, but DVD playback and digitally captured (firewire/HDHR/etc)
TV recordings may have such tracks.

Do you have these settings enabled?  Are you using a digital audio output?

I've also had some problems with cracky noise from the internal DVD
player when I have DTS or AC3 passthrough enabled, even though xine
and vlc seem to support this just fine using the same DVDs.
