Rhythmbox and m4a support

Hey guys, I have Rhythmbox working pretty well right now with my mp3s but it does not seem to recognize my m4a files. I tried to install all the gstreamer-* and gstreamer1-* plugins but there were some compilation errors. Which plugin is the one for m4a support? Thanks in advance.
I believe you should install FAAC/FAAD plugins. They are available as packages, there shouldn't be a need to compile.
Yes, it works now. I simply had to remove the rhythmdb.xml file in ~/.local/share/rhythmbox and rescan my music collection and the m4a files are added and play.
