IFusionSound   CreateStream

Create a streaming sound buffer.

CreateStream (
  IFusionSound   * thiz,
  const FSStreamDescription   * desc,
  IFusionSoundStream   ** interface
);

If desc is NULL, all default values will be used.

Default values for sample rate, sample format and number of channels depend on device configuration, while ring buffer length defaults to 1/5 seconds.
