Optical Out from TV to Sonos Play bar
HDMI Out from Apple TV to TV HDMI1
Airplay music from iPhone to Apple TV and TV needs to be turned on for Sound Bar to function.
Thanks in advance if anyone out there sees my mistake and can suggest a solution where I dont have to turn my TV on.

Basically, your TV won't send any data out through the optical port while the power is off.
Conversely, you could replace your PLAYBAR with a Beam, which has much newer tech in it, including the ability to be an AIrPlay 2 target, which the PLAYBAR doesn't.
