Hi all. I just purchased a Squeezebox Duet, and cannot get any sound through my Squeezebox receiver's coax digital output. I have a set of Cambridge Soundworks 210D powered speakers. It has a digital coax input. When i connect my receiver to them with the digital coax output, I get no sound. When I use the analog RCA output connected to the same speakers into the Analog A input on the speakers, I get sound. When I take the digital coax cable from the speakers, and connect directly to my PC digital output (again I am just disconnecting from the Squeezebox receiver coax output and connecting the very same cable to the very same speakers, but using the PC's digital coax output) I get glorious sound. I have been on the phone with the helpdesk for 1 1/2 hours on this. They diagnosed it was a defective receiver. They sent a new receiver and the exact same thing is happening. Any suggestions are welcome. thanks in advance.
