I have a Panasonic TC-P42S1 tv which only has a digital audio out. I have a Polk soundbar which only has the RCA (red / white, left / right) input. The Polk soundbar also only has one input. The Polk detects sound from any source and works great, but right now I have to run the RCA cables from the cable box to the soundbar when I want to listen to the cable box, and then manually plug it into the Blu Ray, or Wii, or anything else when I want to listen to another source.
I can run all of the sources through the Tv (Cable, Blu Ray, and Wii) but then I can't get the digital audio out from the TV connected to the RCA in on the sound bar. Help.
