No Sound when running Xfinity Cable Box through Onkyo Receiver with HDMI cables.

Question

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?

Success! It’s fixed. Onkyo Customer Service is back in operation. Luckily, my TX-NR727 is not effected with the failure as on other models. Tech had me reset my receiver (hold Cbl/sat tab while pressing the power Button). It fixed the problem but I did have to manually restore all my personal settings

What have you  done To troubleshoot? Switch HDMI cords? Try another HDMI port on your receiver? Try another device with hdmi to the receiver to see if it works? Just basic troubleshooting

Cynthia59 · Answer

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?

If you turn on the tv speakers do you get audio? If you do, you’ve proved the cable box with hdmi is good and may be a receiver setting

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.)
