CEC CONFLICT
Samsung TV & Audio · HW-B650 3.0 Channel 330 Watt Soundbar with DTS Virtual:X and Bluetooth
Soundbar turns on/off unexpectedly, switches inputs randomly, or volume changes on its own. CEC (Consumer Electronics Control) allows devices to control each other over HDMI, but conflicts arise with multiple CEC devices. Common symptoms: soundbar powers on when another HDMI device activates, volume changes when switching TV inputs, soundbar switches to wrong input. Fixes: (1) limit CEC-enabled devices to TV + soundbar only — disable CEC on Blu-ray players, game consoles, etc., (2) toggle Anynet+ off then on again on the TV, (3) use a dedicated HDMI port for the soundbar (the ARC port), (4) if persistent, disable Anynet+ entirely and use optical connection as alternative (loses CEC convenience features like TV remote volume control).
