I'm so close to one-remote perfection. My HDTV is connected to the soundbar via HDMI ARC. AppleTV connected to HDTV via HDMI. When I put the Apple TV to sleep, the sound bar goes off as expected - yay. The TV, though, doesn't. I can't tell if this is an LG issue or an Apple TV issue... I wouldn't know how to reasonably troubleshoot that. Anyone else having this issue w/ a soundbar connected via ARC?
