I have an Oppo-103 connected through HDMI and when I play a DTSCD, any DTSCD from a number of years ago I get the video on my TV (song listing, ,etc) but no sound. I can see the seconds moving along.

I've tried playing around with the Oppo settings but to no avail. For a while I had it going through the coax cable and it was passing 5.1 to the 976 but I'm confused on why the HDMI won't pass it or whether the 976 is not reading it. Does take a few seconds for the handshake to confirm. Get all Master Audio, etc through Blu-ray as anticipated. Curious if I'm the only one listening to these old DTSCDs?
