I have a new sound bar that I want my TiVo box,tv, ps4 and pc desktop running through. The sound bar has an optical input and a hdmi input. At the moment I have the TiVo box hdmi into the Soundbar and a hdmi out to the TV so that means I have to have Soundbar on to watch TV. As I understand a pc with a dvi to hdmi converter in the back means the hdmi carries no sound, so I have picture on my TV but no sound. The way I have got round this so far is to have optical coming from my pc and optical coming from my tv (for the ps4) so I have them into a splitter and an optical into the Soundbar. Now while this works fine I can't have the optical plugged into the TV if I want to watch a film from my pc so I have to unplug it. Also when I watch a film from my pc it sounds very echoey and doesn't sound right. Is there a better way to connect these and fix my sound from the pc
