Keyboard macro to change default audio device

Question

Windows 7, Logitech G110 keyboard

2 audio devices (headphones and speakers)

I am hoping to find a quick way to macro a key to switch to headphones, and a key to switch to speakers.

Anyone have a good program or anything of that nature?

EDIT: Using AHK to try and get this task working as hoped is sadly not doing the trick. I have included a screenshot of my audio set, as well as a screenshot of my script as it sits now.

I have also tried to uncheck "show disabled devices" and modified the script to be Down 1, and Up 1 respectively. It will work for one device, but it refuses to switch to the secondary.

Based off of this article.

1. Download and install AutoHotkey.

2. Open your sound control panel. This can also be done through running mmsys.cpl through the start menu search or the run dialog.

3. Note how far down the list your desired options are. In the following image, the HDMI Output is item 1 and the current default Speakers is item 4.

   

4. Modify the following script. F6 and F7 represent the activation key (F6 and F7) (the * means this hotkey applies even when modifiers such as Ctrl are pressed). The {Down #} command indicates how far down the list to go. From your screenshots, you want {Down 3} for Speakers and {Down 4} for Headset. If you add or remove audio devices, or show/hide disabled items, the number will change.

   *F6::
       Run, mmsys.cpl
       WinWait,Sound
       ControlSend,SysListView321,{Down 3}
       ControlClick,&Set Default
       ControlClick,OK
       return
   
   *F7::
       Run, mmsys.cpl
       WinWait,Sound
       ControlSend,SysListView321,{Down 4}
       ControlClick,&Set Default
       ControlClick,OK
       return
   

5. Run the script. You can set the script to run at startup if you'd like.

The reason I call this a 'hack' is the script actually opens the control panel (a GUI window). Ideally, this could be done through the command line, by specifying the sound device's GUID.

There's apparently a program with a CLI to switch sound devices. You supply the same number in the list, which makes me think it's not much different from the AutoHotkey 'hack' here. In any case, something like AHK would be required to bind it to a hotkey.
