Hi Ronny,
Afaik (and I haven't looked at this myself) the way the DSP plugins in
Maemo work is that they are all sinks themselves. So instead of decoding
a mp3 using an mp3 plugin then outputting the sound to for instance an
alsasink, you just send the mp3 file to the mp3sink and it will also
take care out outputting the audio on the Nokia 770 device.

So the pipeline would look something like filesrc ! mp3sink

Jussi probably have a more exact/correct example than me :)
