ARC makes receiver stubborn
I have an ARC problem I hope someone can help me with.
I have an SR5008 receiver, and I just got an LG television. As before, I have my sources (satellite, Blu-ray, DVD, and occasionally an old Xbox) connected to the Marantz, and then that connects from the receiver's HDMI ARC monitor out to the television's ARC HDMI input.
I can hear the Blu-ray or satellite audio just fine when selecting the appropriate input on the receiver (haven't tried the other two yet), and the video appears on the TV.
When using an app on the TV, I didn't get any sound sent back to the receiver even when I set the receiver input on TV audio.
I tinkered around and discovered that if I go into the receiver's Video menu, under HDMI, and enable HDMI control, I can hear audio that is originating from the TV (testing with the YouTube app).
The problem is when I exited the app, and put the TV back on the input connected to the receiver (actually, it reverted back to it automatically), the receiver insisted on being on the Blu-ray source. I pressed the cable/sat button, and the little round front panel display briefly said cable/sat, but then it immediately reverted to Blu-ray. The TV seems to correctly relinquish its audio connection to the receiver, but then the receiver won't let me choose anything but Blu-ray.
Only when I turned off HDMI control in the receiver's menu could I once again choose whatever source I wanted the receiver to deliver to the TV. But then I no longer could get sound from a TV app.
Is there some obvious thing I'm missing that will let me choose whatever source I want at the Marantz? Why would it insist on Blu-ray like that?
Maybe I'll end up having to go with an optical cable to deliver sound from the TV to the receiver. Sounds like some people prefer that method anyway. This is my first crack at using ARC, and I'm learning it can be a little finicky. I've got a toslink cable and fresh HDMI cable on the way.
