Vudu/Oppo audio problem


I will admit that I am not much of a home theater guy so I have little knowledge of some of the intricacies involved. On occasion we will rent a movie using Vudu which I source through my Oppo 103D. the audio output goes direct to my Dac. When I play Vudu movies I get no audio and have to use the poor quality speakers on my Panasonic TC-P50GT50 Plasma TV. When I play Youtube or some other source the audio is just fine. I have changed some settings on the TV to no avail. Is this a format compatibility issue between the movie audio file from Vudu and the Oppo? I would appreciate any help. FYI, this is not a component connection issue and I have the latest firmware downloaded to the Oppo. Looking for ideas, thanks!

In the oppo setup menu, check audio processing.

You may be sending 5.1 to your DAC when it only handles stereo. :)
Ok, it was set for 7.1 surround. I changed it to stereo, tried the test tone and got nothing. I tried playing a movie and the same thing, no sound.
My Dac displays the bit rate when playing various files. When I switch to Vudu it flatlines indicating no signal.
I appreciate the feedback erik. I tried searching vudu/oppo sound issues on the net in general and on the A'gon forum and didn't find anything helpful. That made me think, alright, this has to be a simple setting or something that I am overlooking. Any chance you could direct me to a link?
There are some free movies you can stream. The link you provided was about connecting to vudu as opposed to the sound problem. Like I mentioned, I can't seem to find anything that addresses my particular issue.
Sorry, I am unable to try your problem at this time. :(

Your alternative of course is to use the stereo L and R outputs from the Oppo.
