How to use Application.EnableSound in the xlwings API way

The EnableSound property of the Application object in the Excel object model controls whether Excel plays sounds associated with certain events, such as alerts or errors. In xlwings, this property can be accessed and modified to manage sound feedback programmatically, allowing for a quieter automation environment or toggling audio cues as needed. This is particularly useful in scripts that run unattended or in environments where sound is disruptive.

The xlwings API provides a straightforward way to interact with this property through the App object, which represents the Excel application. The property is a Boolean value: True enables sound playback, and False disables it. The syntax for getting and setting the property is as follows:

• Get the current state: app.api.EnableSound
• Set to a new state: app.api.EnableSound = False (or True)

Here, app is an instance of xw.App in xlwings. The .api attribute provides direct access to the underlying Excel object model, allowing you to use properties like EnableSound as defined in Excel’s VBA documentation. No parameters are required for this property; it simply reads or writes a Boolean value.

For example, to disable sounds in Excel during an automation task and then re-enable them, you can use the following xlwings code:

import xlwings as xw

# Start or connect to an Excel application
app = xw.App(visible=True)

# Disable sound
app.api.EnableSound = False
print("Sounds disabled.")

# Perform some tasks, such as opening a workbook and triggering an alert
wb = app.books.open('example.xlsx')
# Simulate an action that might produce sound, like an error (commented out to avoid actual errors)
# try:
# # Code that could cause an error
# except:
# pass

# Re-enable sound
app.api.EnableSound = True
print("Sounds enabled.")

# Close the workbook and quit the application
wb.close()
app.quit()
