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.
Gave me an easy solution for switching between my TV and headset audio.
Cons
It does not remember the devices I want to switch between.
This may be a failure of my setup, but now I have to exit and restart the program for it to include my HDMI TV audio in the list.
