Setup is LG OLED CX 55” connected to Apple TV via hdmi. TV ARC connection to Sonos beam/sub paired.
EVERY time I power off my devices (aka turn off the TV and appleTV) and power back on at a later time, I lose the Sound to sonos.
I have to go into the sonos app, click on the zone, click on TV as the source, then go into appleTV and restart the system.
Please help/advise! This is a poor process for the money paid into this setup.

My suggestion perhaps wasn’t clear. I appreciate TV Autoplay is set to ‘on’ by default, but my thoughts were to toggle it ‘off’ and then back ‘on’ again. The TV should then Autoplay through the speaker, but I’m guessing you may have toggled the switch back ‘on’ in any case.
The issue sounds HDMI-CEC related, it’s perhaps best if you can ensure that HDMI-CEC is switched on for the TV and switched off for any other devices connected to the TV, except for the Beam.
With LG TV’s that’s enabling both Simplink and Auto-power-Sync to get things working and ensuring the Beam and nothing else is connected to the TV’s HDMI-ARC port (usually HDMI-2)
The Apple TV HDMI-CEC feature can be switched off in its settings (I believe it’s in ‘Remotes and Devices/Home Cinema Control’
Hope that Assists.
