I received my DS upgrade kit and installed it a few days ago. Playing music via my Mac Mini with Amarra Symphony (with Dirac IRC) via HDMI, the DS sounds fantastic. However, I am having a problem connecting to the digital out from my CD Player – an Oppo BDP-83. I cannot get sound from either the coax or optical connections. When I first turn on the Oppo and select the Coax (or Optical) input, a green light goes on the DS, as expected, indicating a connection, but when I hit “Play,” and the track begins, the color switches to red and I get no sound. Any ideas as to what is going on? I have tried rebooting both the DS and the Opps, with the same results.
