**`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:
```py
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:

| Sound name in `PlaySound`  |   Control panel sound name|
| - | - |
|  'SystemAsterisk' | 	Asterisk
  |
| 'SystemExclamation'  | Exclamation  |
| 'SystemExit'  |  Exit Windows |
| 'SystemHand'  | Critical Stop  |
|'SystemQuestion' | Question |


> 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:

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