Using libcec as proxy for AV receiver - How do I put audio in standby when handled by libCEC? #652

The adapter will do so (I think) if the connection is severed, otherwise its assumed on, the code is open so change it as you wish 😊

If the TV is off I turn the audio off but if the TV asks the power status libCEC always reports on. Is there a way to get libCEC to report "standby" for a device it handles?

I'm using a Raspberry Pi not an external adapter. Not sure which code I would change. |

The source code of libcec and recompile it
