CEC CONFLICT
Sony · Sony HT-A7000 7.1.2-Channel Soundbar with Dolby Atmos and DTS:X
The soundbar turns on or off by itself, switches input sources unexpectedly, or exhibits other erratic behavior when connected via HDMI. HDMI CEC (Consumer Electronics Control) — called BRAVIA Sync on Sony devices — allows devices to control each other through the HDMI cable. When multiple CEC-enabled devices are connected to the same TV (soundbar, game console, streaming device, Blu-ray player), they can send conflicting CEC commands that cause unpredictable behavior. Disable CEC (BRAVIA Sync) on devices you do not need to control mutually. If the soundbar turns off when the TV switches to a non-ARC input, or turns on when you do not want it to, adjust the CEC power-link settings on the TV. As a last resort, disable CEC entirely on the TV and control each device independently with its own remote.
