Sorry I don't understand your patch above. When calling get_frame() or
put_frame(), caller must supply frame size exactly as specified by
port_info.bytes_per_frame of the specified port. I have a felling that
somewhere your code does not do this hence the memory problem.
Also the stereo port was not supposed to support G.711 channel conversion
(i.e. only PCM), if this is what you're trying to do too.
