My TVs HDMI source is Xfinity ,, I feed it to my sr373 Onkyo receiver then to Sony Bravia ,,,TV looks and sounds great through the 373. At times,, I don’t want to turn on the 373, but there is no sound from the TVs speakers. I thought this would be an automatic thing, or that when powered down, the Onkyo would pass the audio through. Is there a way to pass all the HDMI info. through the 373 without powering it up? Is this even possible??
Connect the HDMI output of the Xfinity box directly to the TV and the digital audio output to the receiver. You may need to set the Xfinity audio so stereo outputs via HDMI and surround sound via digital audio out.
