you create two cfg files to register your module?
Normally, the cfg file should be pushed to /system/etc, but /etc should be a
symbol link of the same directory if I remember correctly.
BTW, as JBQ pointed out, perhaps we need move to android platform list to
continue the discussion.

I think you can write a customized MIO which accepts AMR streams and
interacts with DSP directly.

To support a new file format in opencore, basically you'll need 1) A parser

2) A node to connect the parser into player engine framework;
3) A recognizer to identify the corresponding file format;
