Hi roycke, Welcome to Beoworld! I suggest using a separate mains-derived trigger instead of the USB or HDMI signals, this way you have easy control of the trigger signal and there are no annoying pops and clicks through the audio when the trigger voltage changes (as it often does when using USB):- https://soundsheavenly.com/line-in-connection/102-438-minijack-to-beolab-2-7-10-28-and-2500-powered-trigger-kit.html#/2-length-1m Kind regards, Steve.

@roycke I picked up some new B&O speakers at the weekend including a Beolab 7.2 for which the dealer made me up a cable to take the 5v USB trigger from the TV and the RCA pre-out from my AVR to the powerlink socket. I remembered this thread and asked him about the issue of the TV’s USB being ‘always on’ and he said that if a TV has a USB that’s always on then it must have another one that isn’t… not sure if that’s true but could be worth checking? Also if the TV does only have one USB, could there be a some kind of power setting which affects whether the USB is always powered or not?
