I have hdmi-cec enabled on my atv4. Generally it's great because I only have to use one remote to control everything. The one downside is that if I want to only stream audio, it doesn't seem possible without the tv being turned on. If I turn the tv off, everything switches off. Is there any way to play audio without having the tv on and still having all devices connected through hdmi-cec? I tried searching but didn't find anything.
