What audio sink are you using?

This works fine for me with totem and gst-launch-0.10 playbin2
uri=file:///path/to/foo.aac, whether I force output to stereo or pipe all six
channels to the sink, both with alsasink and pulsesink.

So it sounds like your audio output is advertising 6 channels and then just
takes 2 channels and discards the rest instead of downmixing (alsa issue? I've
heard this before, I'm sure..)

You could try changing the gconf musicaudiosink key to something like:

   capsfilter caps=audio/x-raw-int,channels=2 ! autoaudiosink

and see if that makes a difference (may need restart).
