I’am using a raspberry pi with a receiver. Audio goes over HDMI to the receiver. My TV has support for HDMI CEC, but somehow there’s two things that go wrong with it.
When the TV is turned off, and I boot up Volumio on the PI, the TV turns on and switches channel from HDMI 1 to HDMI 2 (which has no input). That is very annoying because I keep changing channels and need to turn of the TV again and again. Because I keeps flipping on every -X. I would like to disable HDMI-CEC on the RPI-side.
When I turn switch the powersocket for the receiver and the USB port on which the RPI is powered. In the first boot sequence there is no audio over HDMI. After a full reboot, the HDMI audio does turns on. This could be some timing issue when the receiver it not yet fully powered after first being switched off. How could I force HDMI audio output? Even when there’s no ‘live’ connection yet in the first seconds. Like what happens in the first seconds in this discribed situation…
Any advise is welcome
