I've got a pretty vanilla setup for my fourth-gen Apple TV: ATV > Receiver > TV. The issue I'm having is that while using the Siri remote to put the ATV to sleep powers off the receiver and TV, waking up the ATV does not turn on the receiver (it does turn on the TV). The volume controls work perfectly. The only issue is that the Siri remote does not turn on the receiver. My equipment is nothing exotic. Samsung TV and a Yamaha receiver, both CEC-compatible, with CEC options enabled. I haven't dived into the remote options in the ATV settings app, as none of them seem to apply. Any advice?
