SYNOPSIS

       #include <roaraudio.h>

       int roar_simple_new_stream(struct roar_connection * con, int rate, int channels, int bits, int codec, int dir);

       int roar_simple_new_stream_obj(struct roar_connection * con, struct roar_stream * s, int rate, int channels, int bits, int codec, int dir);

DESCRIPTION

       Opens  a new stream to the sound server as a independet file handle (not an execed one). This is useful if you still want some meta data or
       the volume to be updated after the stream is open.
