If you can get some very simple example in C where you can decode an MP3
on your audio card, then you can very easily create a libomxil-bellagio
component and it would work automatically with GStreamer through
gst-openmax.

The problem is that ALSA AFAIK is not a good place to develop such
driver. So probably you would have to create your own driver for that.

I'm not sure how such a thing could be possible but perhaps UIO[1] can
help.

Maybe you can ask this question to the LKML.

Best regards.
