SwitchAudio.vbs is a script for switching between two audio devices in Microsoft Windows. You need NirCmd for this script to work (download it here: http://www.nirsoft.net/utils/nircmd.html). Please read my comment in this gist for further instructions.

Preparations:

  1. Download NirCmd:
    x86:
    http://www.nirsoft.net/utils/nircmd.zip
    x64:
    http://www.nirsoft.net/utils/nircmd-x64.zip
  2. Extract NirCmd and place nircmd.exe and nircmdc.exe in the same folder as the other files
  3. In order to get the script working with the default settings you have to rename your Headset to 'Headset' and your Speakers to 'Speakers' (You can do this in Windows's audio devices manager). Or edit the lines in devices.txt to match your devices.

Usage:
Just run SwitchAudio.vbs by double clicking it or bind a hotkey of your keyboard to it
