Can you put the Sky box through the tv with the sound bar connected to the ARC HDMI port?
He's connected like that now?
Unless you mean the Sky box directly to the TV.
He didn't have enough HDMI ports for that.
He currently has the Sky box connected via HDMI cable to the Soundbar HDMI IN socket, and another HDMI cable from the Soundbar HDMI out socket to the HDMI (ARC) port on the TV.
It's currently connected how it's designed to work.
