Coastal Audio Changer makes switching audio devices in Windows 7 a doddle. Version 2 supports both input and output devices, better hotkey support and a process monitor so audio setups can be assigned to particular programs such as media player software like xbmc. Purchase price is 3 US Dollars – which works out about the price of a half a local pint of beer 🙂
You can download the trial here. You’ll need .Net Framework 4 installed from Microsoft. The trial lasts for a few months. Purchase includes the original CAC too. Below is a short video demonstrating how to set up Coastal Audio Changer.
