This function Calls the underlying PlaySound() function from the Platform API. The function needs two parameters. The sound parameter may be a filename, a system sound alias, or audio data as a bytes-like object. Its interpretation depends on the value of flags. The flags are as defined below:

SND_FILENAMEThe sound parameter is the name of a WAV file.
SND_LOOPPlay the sound repeatedly
SND_MEMORYThe sound parameter to PlaySound() is a memory image of a WAV file, as a bytes-like object.
SND_ASYNCReturn immediately, allowing sounds to play asynchronously.
SND_NODEFAULTIf the specified sound cannot be found, do not play the system default sound.
SND_NOSTOPDo not interrupt sounds currently playing.

Following statement plays the given WAV file.

>>> winsound.PlaySound('sample.wav', winsound.SND_FILENAME|winsound.SND_NOWAIT)


The Windows registry keys are associated with sound names.If the registry contains no such name, play the system default sound unless SND_NODEFAULT. All Win32 systems support the following:

PlaySound() nameCorresponding Control Panel Sound name
SystemExit'Exit Windows
'SystemHand'Critical Stop

For example following statement plays Windows Exit sound.

>>> winsound.PlaySound("SystemExit", winsound.SND_ALIAS)
