CreateCommandThread ( ) : void
GetCurrentStream ( ) : MediaPortal.MusicPlayer.BASS.MusicStream	Returns the Current Stream
GetSoundDevice ( ) : int	Get the Sound devive as set in the Configuartion
GetWasApiFormats ( ) : void	Detect the supported output formats for WASAPI
GetWasApiSpeakers ( ) : int	WASAPI doesnj't provide a way to ask the driver on the maximum of supported speakers. So we try to enumerate the channels and detect the attached speakers.
HandleBassError ( string methodName ) : void	Displays Information about a BASS Exception
HandleCueFile ( string &filePath, bool endOnly ) : bool	Parse the Cue file. Return a Fake Cue track and adjest the playback position within the file.
