CEC Troubles, Receiver not waking from standby

Hi all,
I’m running into the following issue: my receiver has ARC-CEC all the good stuff.
When Volumio stops playing it goes into standby after 10 minutes, which is exactly what I want.
The only issue now is that starting playback on volumio again does not wake the receiver from sleep.
Any help would be appreciated :slight_smile:
I know I can work around with wifi-enabled socket plugs etc, but what I want here is a feature that should be working, right?!
