I had a play bar that turned on every night at 2am by itself. It is hooked up to an RCN 4K android cable box optical out. I had to return it . Bought a Yamaha yas-408 sound bar , hooked up identically and never had a problem . Didn’t like the sound quality so I bought an ARC sl hooked it up identically and low and behold it turns on at 2am again. Beyond frustrated.Sonos and I checked for alarms which there are none.

That suggests that the cable box you have the sound bar (either one) is connected to is waking up, probably in order to check for software updates.
Connect the Arc to your TV, instead of the cable box, and make sure the TV’s software is up to date. Or check with the maker of the cable box to see why it is powering the output while it checks for new data.

Hi. There will be something in your setup external to Sonos that is causing this. Sonos products are just not going to do this unprompted. Do you have any other control systems in your home, e.g. Alexa, Homekit?

Good thought Bruce.
Thank gentleman, I think my first order of business is I will unplug the google assistant and Alexa tonight , to rule out that avenue. Looked to turn off auto play on the Sonos app and could not find it
Thanks so much John, turned of ungroup on auto play and auto play and as I said I will unplug google assistant and Alexa tonight so well narrow from there. Again thank you
