This shows you have installed faad plugin successfully. I don't have any
idea why its not working .
But you can try following combinations ;
gst-launch filesrc location=filename.aac ! decodebin ! audioconvert !
alsasink
gst-launch filesrc location=filename.aac ! decodebin2 ! audioconvert !
alsasink
gst-launch filesrc location=filename.aac ! qtdemux ! faad ! audioconvert !
alsasink
gst-launch filesrc location =filename.aac ! decodebin ! faad ! audioconvert
! alsasink
gst-launch filesrc location =filename.aac ! decodebin2 ! faad ! audioconvert
! alsasink
