Hi I have upgraded to a new Onkyo 626 and often find there is no sound from switching to TV/CD ie sound coming from the TV to the amp. ( I use the SAT/CAB for my satellite box ) It's not all the time and sometimes it flashes PCM and MUTTING on the amp. I found that I have to turn on and off the CEC RHID setting to get the sound back. I never had this issue with my earlier Onkyo 509. Any ideas??
