What is winsound.SND_ALIAS in Python?

winsound is a module in Python that enables the sound-playing mechanism in Windows systems. It includes several functions and constants, one of which is the SND_ALIAS constant.

PlaySound method

PlaySound is a built-in method of the winsound module, which allows us to play any sound. The syntax of the function is:

PlaySound(sound, flag)

The sound parameter can be a filename, audio data as a bytes-like object, or None.

The flag parameter is used to provide a value to interpret the sound.

SND_ALIAS

SND_ALIAS is one such flag used in the PlaySound function, which can be interpreted as a control panel sound association name. Following are the basic sounds supported by a Win32 system:

If the sound name is not registered, the system default sound is played unless SND_NODEFAULT is specified.

Example

The following piece of code plays the windows exit sound:

import winsound
# Play Windows exit sound.
winsound.PlaySound("SystemExit", winsound.SND_ALIAS)
