I have my 950's CD input to use OPTICAL1. I have had it set this way for well over two years. Today, I hear an electronic click (like a short in the speaker wires) and the sound goes off. I can flip it to ANALOG and things are fine (I have both hook ups set up). So, I know the signal hasn't gone away. If I unplug the optical connection and connect it again, no change.

I haven't figured out what I do to get it working again, but the audio on the OPTICAL1 comes back either when I futz with A/V settings or when a new song starts up or when I flip between different sources.

So, I ask you all...

Any ideas what is wrong?

No changes have been made to any configuration in months.

Thanks for any ideas.
