Normal Marshmallow Firmware has an option to switch OFF HDMI-CEC completely, this is missing with Mi Box MM Firmware.
To make matters worse they seem to have stuffed up HDMI-CEC behavior with the latest Firmware update. My TV no longer Autoswitches ON and selects the correct HDMI input when the Mi Box wakes up from sleep. This used to work before.
I have none of those remote channel change issues and problems you describe on my 2015 HiSense 55K321UW.
