Regarding your mention that the device will be turned off when switching Activity, CEC may also lead to device switching state conflict, it is recommended to turn off the CEC function of the device. Avoid sending commands to the device via HDMI as well when other devices are turned on/off, this may duplicate with activity commands and lead to control exceptions.
