Im trying to connect my boss sound system to my panasonic viera 42 inch plasma tv. my boss has only RCA, but the only sound out on the tv is the digital out! how do i hook up my boss to my tv?

You can purchase a brand "Gefen" optical digital audio to analog(rca output ) converter........they cost $70 to $90 just google that and you will find. If you are usind a cable or Satellite box,you could easily get the analog audio from those audio outputs to circuimvent the problem
