TV: UN65MU6300
setup: I used "universal remote" and set up my soundbar via optical.
When watching the native TV app, OneRemote can control soundbar volume.
issue: But when I change input to HDMI 1 (chromecast with google tv, displayed as "unknown"), OneRemote doesn't send any signal to soundbar. The TV just displays "Audio Out/Optical" but soundbar volume no longer changes.
