TLC 4k Ruko tv (4 hdmi 1 is ARC) ,Samsung Blue Ray Player, Xfinity box all need to get sound to Yamaha surround sound unit, have cable box and blue ray connected to yamaha then from Yamaha to TV using ARC, everything sounds great but cant get audio from streamed channels, assume I need to use another hdmi connection from tv output to a different input on Yamaha and switch to go to streaming is there any other way to avoid the switching?
ARC saves you from having to ran an optical audio cable from the TV to the receiver but you will still need to change the input on the Yamaha.
You may need to turn ARC on in the TV menu. It isn't on by default in many cases.
You may also need to assign ARC to an input name in the Yamaha input menu.
Check the owners manuals.
