switchaudio-osx 0.0.1-unofficial (new formula)

This formula provides the OS X command line utility
SwitchAudioSource. Users will be able to switch audio sources
(input/output/system) using the command line and without needing
a GUI tool. It works with 10.7 Lion, 10.8 Mountain Lion, and 10.9
Mavericks.
Hi there.  I'm Devon, the original author maintainer.  I tagged this version 1.0.0.

I re-created the official repo to avoid any confusion.  It is https://github.com/deweller/switchaudio-osx.

Thanks for adding this.
