How to detect default audio output device change in Windows
To detect when the default audio output device changes in Windows, you can use the win32gui
and win32api
modules in Python.
Here is an example code that demonstrates how to detect the default audio output device change in Python:
pythonimport win32gui
import win32api
# Define the callback function for device notification messages
def callback(hwnd, msg, wparam, lparam):
if msg == win32gui.WM_DEVICECHANGE:
if wparam == win32api.DBC_DEVNODES_CHANGED:
print("Default audio output device changed")
# Register the callback function to receive device notification messages
win32gui.RegisterDeviceNotification(0, None, win32gui.DEVICE_NOTIFY_WINDOW_HANDLE)
# Start the message loop to receive messages
while True:
win32gui.PumpWaitingMessages()
In this example, the win32gui.RegisterDeviceNotification()
method is used to register the callback function to receive device notification messages. The win32gui.PumpWaitingMessages()
method is used to start the message loop and receive messages. When the default audio output device changes, the callback function will be called and the message "Default audio output device changed" will be printed.
Note that this code assumes that you are running it on a Windows machine and have the necessary Python modules (win32gui
and win32api
) installed. If you are using a different operating system, or if you do not have the necessary modules installed, this code may not work.
