Bose's Smart Ultra Soundbar reset article covers two actions. A reset for minor processor faults is: turn it off, disconnect power from the soundbar or the outlet (and from any bass module and both surround receivers), wait 30 seconds, reconnect and wait about 30 seconds for the reboot; settings survive. The factory restore first removes the product from your Bose account, then holds Play/Pause and Volume - on the remote for five seconds until the whole light bar blinks twice and glows amber.
