    libbanshee: Add an audioresample element to the transcoding pipeline
    
    This fixes transcoding for audio files with a non-standard sampling rate.
    
    Credits go to Tim-Philipp Müller for the analysis of the problem and to
    David Nielsen for his persuasion.
    
    Fixes bgo#635698
