I posted this as well over in the Sony TV owners thread, but I thought better of it and posted it here as well. If this violates some posting rule, I apologize and kindly ask the moderators to delete the duplicate post.
I'm stumped a little bit and need your help. I'm trying to get ARC to work properly. All cables are certified high speed Monoprice.
TV: Sony 900F
Receiver: Yamaha RX-V485
Blu-ray player: LG UBK80
Streaming box: Apple TV 4k
Cable box: Arris
All devices are hooked up to the receiver through individual HDMI ports and the receiver is hooked up to the TV using the ARC hdmi port. I disabled audio passthrough in the receiver so it plays the sound and nothing can come out of the TV speakers. I turned on CEC in the TV and the receiver to enable ARC. CEC is turned off in the Apple TV and there's no options anywhere to change CEC in the LG blu-ray player of cable box. I'm disappointed that LG doesn't have any CEC options to manipulate.
Everything works exactly as it should except for one thing: When I play a blu-ray disc, the receiver changes the sound input from the blu-ray player's HDMI port to the port the receiver uses for ARC and no sound comes out. When I manually change it back to the blu-ray HDMI port while the disc is playing, the player stops playing the disc.
Sound works as it should when playing content from the Apple TV and cable box.
Is there a setting I'm missing, or this is just the consequences of CEC and ARC?
It seems like this created some infinite sound ARC loop. Could this in any way damage my system?
Thanks in advance for your insights.
Edit for clarity:
ARC assigns audio to "AUDIO 1" (on receiver). If I select cable box on my receiver (HDMI 2 on receiver), sound from my cable box comes out from the tv source (HDMI 2 on receiver). If I select Apple TV (HDMI 3 on receiver), sound comes out of the Apple TV (HDMI 3). If I select my tv's native app, ARC changes sound to AUDIO 1. If I select blu ray (HDMI 1 on receiver) and begin to play a disc, sound switches to AUDIO 1 and no sound comes out. When I hit HDMI 1 to try to force sound, the disk stops playing. Super weird.
It makes no sense that 2 devices work fine but 1 doesn't.
