Sometimes life gets busy and things you intended to do pass you by. I wrote a post nearly a year ago on a utility to programmatically change the default audio device in Windows 7, but forgot to follow through and post the code.
Thanks to a reminder from someone who found this post useful, Deliang Ye, I have put together a small GitHub repository with all the necessary code for this project: https://github.com/aifdsc/AudioChanger.
I hope someone else can find this useful as well!
