No Sound when running Xfinity Cable Box through Onkyo Receiver with HDMI cables.
I have run my Xfinity Cable box though my Onkyo Reveiver for uyears with excellent results. Recently, I have lost sound. I had to run HDMI directlt to TV and use Optical Cable to get sound to the reveiver. It works OK but I lose a lot of functionality. Have other lost sound using an HDMI pass though? Solutions?
