I'm using my Harmony remote to turn on my Denon AVR-1713 receiver and Samsung UN60F8000 TV. I am using antenna to watch television and they are connected via HDMI - ARC.
It works fine 75% of the time. Sometimes however, there is NO audio. If I turn off the receiver, the TV will revert to its internal speakers - but if I turn it back on then the sound cuts out completely.
Any ideas? Hard enough to reproduce in the first place, but very annoying when it happens!
