I am trying to hook up my TV audio output to attach to a DAC. Do I need a cable (Toslink or Coaxial) and if so where to I plug it in on my TV. I am trying to attach a sound bar to increase my ability for a higher volume on my TV listening. The soundbar I have has a built in 3.5mm jack, and L and R plug in jacks. This TV is new and I don't get it. I also have a Pc Audio In jack on side of TV. I would appreciate some help!
