I recently purchased a zgemma H9 and I have a Soundbar connected to TV when my H9!is in standby mode and I turn on TV the Soundbar won't turn on via HDMI arc. To get it to turn on I have to turn zgemma H9 box on first before turning TV on

Also when zgemma H9 is unplugged from wall socket Soundbar comes on ok. Does anyone know what setting in zgemma HDMI CEC I need to change so that I don't have to turn on zgemma first.

Hope someone can help.

Thanks
