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.

The fact that it works for CD suggests that the DC-1 input is OK but that it may not be getting the signals it needs from the other sources. What does BYPASS do? The downloadable manual doesn't say.

A two channel DAC will NOT decode a multichannel signal, which is in a different format.
The data stream from your player is in the two channel CD format for CDs, and other codecs for other types of disc.
You would need a receiver with digital inputs (which can recognize and decode those non-two channel codecs)
OR, a BluRay or DVD player which will change the multi channel coding into the two channel code and THEN output it to the two channel DAC. (My Technics DVD-A10 player does this via a menu in the player)
This is an AV receiver (6.1), so why would it need a two-channel signal?

"Bypass " bypasses effects such as Logic 7, Panorama, etc. The issue is unchanged with or without effects. I suppose that was an extraneous detail. Sorry for any confusion.
