Try pressing the up and down volume buttons a few times (not simultaneously). My friend's iPad2 had the same issue and moving the volume up and down a couple of times seems to work.

This is an old post, but I had this problem recently and wanted to share the solution I found on another thread...
Purchase an RCA ground loop insulator (via amazon or radio shack) - it solved the problem.
