Thru my Google Home, I can turn on/off my Hitachi Roku tv (approx 40"), and even change inputs (hdmi 1, hdmi 2, etc.), but when I ask the Google hub/assistant to change the volume on my Roku, it tells me that my Roku (tv) does not support this. After doing some web searching, everything I find says it should support this... does anyone have any suggestions. CEC is turned on, all advanced features have been enabled, even though I do not know what half of them do!
