Need some help getting volume control onto my sky Q remote. I have just bought a new TV and want to use a soundbox but cant get volume control set to my SkyQ remote. It worked fine on my previous TV but not now. The soundbox/bar is a Panasonic SC-HTE80. I had it connected to a Panasonic Full HD 42" TV and was able to control volume ok with SkyQ remote. So yesterday I bought a new Sony Bravia KD49XF8096 4k HDR TV and want to use the Panasonic soundbox. I think I have it connected same way as before. The sound is coming through the soundbox ok but I cant adjust it via SkyQ remote. The soundbox has 2 HDMI ports. One is marked BD/DVD IN the other is marked TV(ARC) OUT. So I have a cable running from TV (arc) OUT to HDMI 3 ARC on the TV. I then have an HDMI running from the SkyQ box to HDMI 2 on the TV. I think this was how I had previous TV connected but maybe I'm wrong any ideas?
