I’m trying to connect my ATT U-verse cable box to other devices (TV, X-box 360, and Roku) while using my Vizio soundbar. I was able to connect the cable box and soundbar (optically) and I can watch and listen to TV (no problem). I also connected my wireless turtle beach headphones to my x-box and I can hear TV, X-box, and Roku thru my headphones (again, no problems). However, I cannot hear the x-box or Roku through the soundbar. When I change my input on the TV to either X-box or Roku – the only sound from the soundbar is from whatever channel is on the TV. Any suggestions? Much appreciated.
