I'm trying to attach external PC speakers to my 32" Samsung Smart TV. The TV only has Toslink audio output. So, I've attached a digit-to-analog converter. However, all that I get is a staccato-like noise as soon as everything is attached. This occurs if the TV has or has not been set for external speakers. If the TV is set for external speakers, the noise occurs, but there is still no TV audio. All components (TV, speakers, and converter) are plugged into the same powerbar. Does anyone have any ideas on how to solve this issue?
