void Audio::Mixer::playInputStream ( SoundType  type,
SoundHandle handle,
AudioStream input,
int  id = -1,
byte  volume = 255,
int8  balance = 0,
bool  autofreeStream = true,

Start playing the given audio input stream.

Note that the sound id assigned below is unique. At most one stream with a given idea can play at any given time. Trying to play a sound with an id that is already in use causes the new sound to be not played.

type the type (voice/sfx/music) of the stream
handle a SoundHandle which can be used to reference and control the stream via suitable mixer methods
input the actual AudioStream to be played
id a unique id assigned to this stream
volume the volume with which to play the sound, ranging from 0 to 255
balance the balance with which to play the sound, ranging from -128 to 127
autofreeStream a flag indicating whether the stream should be freed after playback finished
permanent a flag indicating whether a plain stopAll call should not stop this particular stream
reverseStereo a flag indicating whether left and right channels shall be swapped
