HDMI ARC has stopped working!
After working fine since I bought the TV, and with me making no changes to anything, today HDMI ARC audio is not working.
Usually when selecting a source app on the TV (Netflix, Prime, whatever), the receiver will automatically switch to the ARC input and there's audio from the receiver.
Today when doing the same, a) the receiver does not switch, and b) if I manually select the ARC input on the receiver, there's no audio (nor from the internal speakers in the TV, so it must "think" it's sending ARC audio).
I wonder if the TV did a s/w update overnight which has screwed ARC.
Anyone else seeing similar behavior?
