Subject: Added a radio to 2 channels playback .json example

This files is an example on how to make the softmixer
directly read from a capture device.
In that particular example, the capture is the radio
capture of the kingfisher board, and the playback is
the ak4613 codecs.
The stream rate and format must match the capture capablities.
