Audio/Video not working when A/V Receiver turned off and on

I’m having trouble with audio/video output after I’ve turned my a/v receiver off for a few hours and back on again. Once I turn the receiver on I often don’t get a picture and I always don’t get sound back. I used a Pi1 with osmc and never had the issue with the same receiver. Tried disabling screensaver but that didn’t help. Any help would be appreciated.

Just to test: does plugging in directly to the TV remove the issue?

Does it matter how long you leave the AVR and TV off for?

Have you tried powering TV first, then AVR some seconds later? The AVR may be sending a false EDID until the tv presents one.

Some logs when the problem occurs will show me what’s going on.
