So I’m having some problems. I have my roku using a digital optical cable to my sound bar and it’s nice and loud. Works awesome. The reason I have it like this is because if I use my tv to sound bar it only goes to 40 which is not loud at all. But I’m getting tired of swapping the cable to my ps4 or my Tivo. so I purchased a 3:1 splitter. But can’t seem to get it all to work. Should I have bought enough a switch or am I going to HAVE to use my tv?
