I have stereo speakers connected to my PC, but sometimes I want to take my music to another room via a Bluetooth speaker or at night I want to listen to my headphones without disturbing others around me. Switching between audio devices requires multiple clicks through multiple settings menus. What a pain!
To the rescue is a small (275KB) program called Audio Switcher. This clever little app installs in seconds and is a breeze to set up. Best of all it lives minimized in the notification bar of your Windows machine and can be set up with hot keys to quickly switch between audio devices.
Just for good measures it also works in Windows 10. Worthy of a PayPal donation (Confirmation number: 4PF88076BC623104F).
