Coastal Audio Changer is a handy utility that was created in order to help people that have two or more audio devices on their Windows 7 machine such a set of speakers and a USB headset.

To change between them you normally have to right click the volume icon in the system tray and load up the sound section of control panel, select the new output device, hit default and hit ok. That takes ages. Coastal Audio Changer will sit in the system tray as nice shiny blue icon and with a couple of clicks flick between devices.
