I'm using GStreamer 0.8.5 and gstreamer-plugins-extra-audio-0.8.3 package for AAC decoding.
Hmm, it seems to me that there might be some confusion in this thread about *.aac and *.mp4/*.m4a files, the former can be tagged with ID3 (Winamp does this on default, but it's not a standard method) while the ladder must be tagged with iTunes-compatible tags like the ones that FAAC and FAAD2 would use.
Furthermore I'm not sure if the gstreamer plugin based on FAAD2 also enables the playback of *.aac files, because I read a related bug report that gstreamer would not include an AAC parser for plain *.aac files yet, only one for QuickTime (which obviously means the MP4 container format):
Anyhow, you could always mux existing *.aac files to *.mp4 with the command line tool mp4creator, so that gstreamer and related apps like rhythmbox should be able to play them. But this would remove existing ID3 tags from the *.aac files. If you encode with FAAC, you can produce new *.mp4/*.m4a/*.m4b (audio book) files with the -o switch using the desired file extension. You can also tag them with the appropriate command line switches, see the help screen.
