How can I configure my A/V Receiver for audio return?

Episode 1357 (1:30:56)

Joe from Sounthbend, IN
Yamaha RX-V379BL 5.1-Channel A/V Receiver with Bluetooth

Joe installed a TV, Blu-ray player, and a Yahama A/V receiver for his friend, but they couldn't get the audio return channel to work. Leo says one of the HDMI ports on the TV should be labeled ARC. They'd plug that into a port on the receiver, and usually it just works. Joe went through the settings in the Yamaha and he had to turn on HDMI control. After doing that, the Blu-ray player now wakes up anytime he changes the input. This is called CEC, and it automatically turns on the TV and sets the input to that device when you turn it on. What happens, however, is that everything that's connected tries to switch the TV's input to it when you turn everything on.

Joe wants to know if it's possible to turn off CEC for the Blu-ray player. He apparently has to have CEC on for the audio return to work. Leo says those shouldn't be coupled, but maybe it has to signal to the receiver that the audio is coming from the TV. The chatroom says to turn off all HDMI control of CEC, and TOSLINK may be the option here. That will avoid the whole issue but then he won't get the audio return.
