LG 55" C7 OLED is messing w/ analog out on BD discs?
I was a happy camper driving my old Pioneer Elite Pro-1000 HD at 720p component and playing BDs in 5.1 analog out into my (equally ancient) Anthem AVM 20. Unfortunately the Pioneer gave up the ghost and now I'm driving the OLED through HDMI. This has resulted in a marked deterioration in the analog sound of a number of discs I've tried: the Bourne Trilogy, Apocalypse Now and Star Wars IV-VI in DTS-MA 5.1.
I have CEC off in the Oppo, can't seem to do that on the TV. I've tried HDMI1 and HDMI2 and flipping various other settings, to no effect. Right now I'm listening to "Totally Ripped", the Olympia set. I can tell that the TV's HDCP is active because audio is temporarily absent when I turn off the TV. But this disc sounds fine, so presumably it lacks some copy protection the others have.
I can't say I'm shocked: I was worried about some HDCP interaction when I replaced the TV. I'm waiting for the HDMI upgrades on the Emotiva XMC-1 this summer to change pre-pros. Am I stuck until then, or am I missing something in the settings?
P.S. Was I ever wrong! The TV screen was causing the problem! It is larger than the Pioneer was (55" vs. 50"), mounted a few inches higher and tilted slightly down. The Pioneer was mounted dead flush and had a heavy moulded plastic frame. We sit 12' away on a couch against the wall. The TV was literally (and efficiently) beaming doubly and triply reflected center channel sound directly at us. So it was disproportionately affecting movie discs that were heavy to center channel. Luckily I was able to move some things around to increase the direct center channel sound and more or less restore the balance. I knew that screens were a big acoustic problem, but it never occurred to me that the sum of some minor changes could cause significant changes in the acoustics of a largish room.
