No sound for DVD, Blu-Ray, or Cox via digital.

Sony Blu-Ray BDP-S360
Lexicon DC-1 Digital Controller
2 Rotel RB-980BX powers amps (2x120 each)
Pair of Sony SS M3's (vertically biamped)

I use no effects, equalization, loundness, etc. The DC-1 is set to "Bypass." The Blu-Ray player is connected to the DC-1 via toslink. Unfortunately, I only get sound using this connection when playing a cd. If watching a DVD or Blu-Ray, I have to switch to rca's--same thing for my Cox Cable box. I contacted Lexicon Support, and they essentially shrugged. Is it worth taking the DC-1 to a repair shop to update something (is it the dac)? Am I instead better off waiting and replacing the unit down the road? Any guidance is much appreciated.

Then, on the other hand it may be the Sony is screwed up. No way to know which product is not sending the signal?
After all, SACD will not transmit via digital output, and you BluRay IS a Sony... 8^)

It's not the Sony. Coax and Toslink just don't have enough bandwidth for hi rez audio. HDMI will pass the signal of both SACD and DTS HD etc digitally. And the processor must be able to decode the signal.

As I said, the TOSlink input is working and should be able to handle DD, dts and regular PCM/stereo. Since it is not, I would suspect that the sources are not set up properly. If they have HDMI outputs, they probably default to sending the audio to HDMI and not to the digital coax/TOSlink outputs. Check the setups for the BR player audio and the cable box.

Thanks very much for the replies. Based on the troubleshooting I've already done, the suggestions to set up the sources properly have a real ring of truth. I'll embark on that project asap and report back. Many thanks!

I set up both the cable box and Blu-Ray. Cable had two options for the Digital Out: Two-Channel and DD. No change/sound. Blu-Ray is the same story. I changed the Digital Out to PCM, but it had no effect. A red light flashes on the Lexicon indicating a signal it cannot process.
