Seeks audio to given time. Does not work if audio has ended.

MixPlayer.setPlaybackDevice(Number index)

Set the playback device to the device at given index of MixPlayer.getAudioDevices(). Note that if the specified device disconnects, then output device is not automatically changed.

MixPlayer.destroy()

Destroy MixPlayer, uninitializing the player and removing the callback loop, to safely exit the program. MIXPLAYER CANNOT BE REINITIALIZED!
