This should probably be in the AV section but wanted as many views as poss,obviously mods feel free to move it Right I have my sky box plugged into hdmi 1 on the TV, soundbar into hdmi 2(arc) and yesterday added a hdmi splitter, 2 into 1, into hdmi 3, xbox and blu ray player go into the splitter, I tested it yesterday and the splitter worked great, it takes power from the blu ray player or xbox and has a toggle button to switch between the two. After a quick test, picture and sound worked great, I turned the xbox and blu ray player off and put the sky box on, no sound from the soundbar? I checked and re checked cables and I hadn't changed any TV settings but still no sound. Only thing that's changed is the hdmi switcher so I removed it and bingo, sound. Any ideas anyone? Ta Jim
