Switch default audio devices on Vista and Windows 7.
Default Audio Changer is a program that can change the default audio device on Vista and Windows 7. It is especially useful if you have a sound card with speakers attached and a USB headset or headphones.
It just does what I need it to. A simple program that works properly
Cons
In my particular situation (I have an HDMI screen, instead of a computer monitor) I have to turn on the screen for DAC to recognize my monitor. Otherwise, it will only recognize my headset. That means I have to close and start the program again.
