I have a Yamaha CX-1000 preamp and I just acquired a used Yamaha CD
player that has a digital output (CDX-710).

The CX-1000 preamp has digital inputs on it. Even though this CD
player sounds fine through the analog outputs, I wanted to hear what
the digital output sounded like.

I used a Monster Cable Datalink SP/DIF cable I had lying around to
connect the two.

PROBLEM: I get perfect audio through the left channel, but nothing at
all in the right channel. Needless to say, the CD player sounds great
in BOTH left & right channels when I use its analog outputs.

What could the problem be?

The problem is a fault in the sending device, or the receiving device.

So which is it holmes? The Sending Device of the Receiving Device?

The sending device might be coding the datastream as a mono feed, or the
receiving device is failing to decode the datastream as a stereo feed. It
might be something as simple as a configuration problem (one of the
devices is set to 'mono'). To diagnose a fault, use a protocol analyzer,
or a process of elimination by substituting components until you get
something that works.



Even if it were, that would not result in the loss of one physical channel's
reproduction from the amp. What you would have is both left and right
channels combined into one single mono channel, which would then be
identically coded onto both left and right channels, within the single
SP/dif data stream. So you would get two channels physically reproduced, but
each containing the same mono audio.
