Apple TV Gen 4 Audio
On the old Apple TV I used the toslink output from the Apple TV for the sound but on the new Apple TV there is no audio output. So I set up the recommended solution for connecting to the sound system, i.e. connect the sound system to an Airport Express and stream the sound from the Apple TV to the Airport Express. It works like a charm but I have to reconnect it every time I want to use it - when the Apple TV has gone to sleep, the audio is reset to the default and that is Apple TV which for me means no sound. Really annoying!
Am I missing some setting to make this configuration work as expected?
