Here's one you can try: http://www.xciv.org/~meta/audio-shootout/emerge.m4a It plays fine with mplayer, and faad can decode it to wav just fine. # gst-launch-0.10 filesrc location=emerge.m4a ! decodebin ! audioconvert ! audioresample ! alsasink Setting pipeline to PAUSED ...

Created attachment 104543 [details, diff] gst-inspect-0.10 output I should also mention that I'm not sure whether this is a new bug or regression, I haven't tried to play an m4a file for several months.

The problem is that to decode m4a files, you also need the qtdemux plugin.. Part of the gst-plugins-bad package. Which rhythmbox should require too. Once I install gst-plugins-bad, I can play my m4a files.
Thanks, that fixes it.
