Audio to receiver question please
My current setup: TiVo Roamio on Xfinity cable. HDMI cable to Yamaha HTR-4065 receiver and then out to Samsumg 65" 1080 TV. Works great and I can control on/off and volume from my beloved TiVo "dogbone" remote.
Problem is TiVo streaming is weak nowdays (no Disney+ etc.). I'm looking at a new Samsung QLED 7 series 4K unit that will have all the built in streaming players. If I get this I then need the audio to go from the TV to the receiver, instead of from the TiVo to receiver.
What would be easier or preferred: HDMI from TiVo to TV then HDMI ARC to receiver, or optical from TV to receiver? Is one better then the other for audio sync issues? If the audio is comming from the TV, what remote do i use for volume?
