Hi, I have altec lansing fx 6021 speakers I use with an old mac  book pro. Suddenly, the right speaker stopped working and the problem -- I believe -- is coming from the right jack on the subwoofer. Both speakers will work out of the left speaker plug, But nothing will work out of the right speaker plug.
Any Suggestions? Thanks, David
