Because a Samsung LED TV and an "old" audio system had a converter forth from digital to analog RCA LR. Amazon has delivered overnight, and that part works fine in good quality. However, there it's a pretty loud noise, while no optical input comes, so each time you switch! The have already written some here, but I think there's so much that you have to pull more than one star.
I turn on the system only for moving one because it tremendously annoying when zapping and the Katz investigated the width while otherwise on the couch and classical concerts like listening.
