I have a number of DVD xvid rips containing a 5.1 Dolby Digital signal that play fine across my LAN on my old xbox running XBMC, but don't play audio correctly on the boxee box regardless of what setting I use.

I am using the SPDIF connector to send an audio signal to a receiver that has always handled Dolby Digital signals just fine, until today.

No matter what setting I use, I cannot get the receiver to recognize a 5.1 signal from the boxee box. The setting that should work - Digital (S/PDIF) with Dolby Digital Capable Receiver checked - produces no sound at all. The only way I can get these movies to play sound through the receiver is to select Digital (S/PDIF) or All Inputs and leave all the output options unchecked. That gives me sound, but only in stereo.

I've rebooted the box after changing the audio settings (as was suggested by someone else on the forums with an audio issue), but that didn't seem to make any kind of difference.

Are others able to get a 5.1 signal to a receiver using a similar setup? Any suggestions?
