Need some basic help on reconfiguring AV setup
hey folks, first post here and I'll apologize in advance for what I'm sure is a dumb question.
We've had a 5.1 system in place for a few years. It was a Samsung 55" tv, an Onkyo TX NR-737 receiver and a 5.1 speaker system. We connect a Dish Hopper 3, a 4k Apple TV and a DVD player to the receiver and then a single HDMI cable to the TV. Worked great.
We just upgraded the TV, bought a Vizio P65-F1 and it looks terrific but a few issues. We hooked it up the same way we had the Samsung hooked up, but this tv is ARC compliant so had an HDMI cable going from the ARC HDMI port on the receiver to its equivalent on the TV. Everything looks and sounds great except for two issues:
- the ARC functionality doesn't seem to be working, if I select the TV's SmartCast source as the input and stream, for example, a youtube video, the sound plays through the TV, not the receiver.
- When we select the receiver's input as the Dish Hopper, the TV shuts off about every 15 minutes, just like someone hit the power button. We turn it back on, wait 20 seconds for it to boot back up and away we go until it does it again. Maddening. We do NOT have this issue when the receiver's source is the Apple TV.
So I did a test, connected the HDMI from the Hopper directly to the TV and the TV doesn't shut off, so the powering off issue seems to be receiver-related. Weird. But obviously I'm not getting sound through the receiver now, just the tv.
So I've ordered an optical cable which arrives tonight. I was thinking once it does I'll plug it in, then connect the Apple TV's hdmi cable directly to the tv as well and then hopefully all is well. I'll get sound through the receiver and no more powering off. But something that confuses me is what will I need to select as the receiver's source. Does it matter or will it just automagically "see" the optical cable and when the tv is selected to a given source it will then just play that audio through the receiver? I have visions of connecting the optical cable and still not having sound through the receiver for a reason that is simple if I'd just asked ahead of time. Hence, this post.
My main purpose here is to get an answer to that last question but if anyone has a clue why the tv was powering off while playing the Hopper but not the Apple TV, I'd love to hear more. I find that perplexing.
