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?
Solved! Go to Solution.
Yes thanks for the trouble shooting suggestions. Did all of that and wih the Xfinity Tech verified it is not a cabling or connection problem. ANy other thoughts?
You may want to check to ensure the sound coding is the same on both devices, PCM or Bitstream.
What model Onkyo? Several models have an issue where the HDMI board goes bad and loses sound, although it can affect the entire system. I just replaced a TX-NR609 that ran into this a few months ago (out of the extended warranty Onkyo had for the issue.)
