I am using the Helix/RealPlayer engine and the RealPlayer has the required plugins and plays .m4a files without any problems, but when I try to play them in amarok, I get the error:

Helix Core returned error: Missing Components

I'm under then impression that since RealPlayer can play m4a's and since amarok is using the RealPlayer engine, than it should be able to play these files.  Anyone have any insight?
