If you are having any trouble whatsoever with timeouts and you’re using a source with a 12v trigger I would not hesitate - get yourself 12v trigger power strip like an IoT Relay and be done with it. Use the remote or home automation to control power on the source and the speakers will just follow along.
Seems like this is a common problem with audio electronics at any price point.
