I’ve seen mentions online about the “no signal” issue with running an AppleTV 4K through a Sonos ARC with relation to “boot up order” but I haven’t seen anything that actually mentions the boot up order or more importantly how to force the boot up order.

Is there a setting, or delay on the Arcana that I can set to control the boot sequence? Sometimes I boot up the system and it works, other times I have to manually cycle the power on the Arcana in order for the signal to get picked up.
