Following up to my earlier post (https://social.omgmog.net/2023/fiddling-around-with-a-convoluted-method-of ) I've got a less convoluted method of handling switching audio output devices from a macro keypad now.

I'm now using Hammerspoon https://www.hammerspoon.org/ -- a powerful tool that lets you define all sorts of automation using Lua. This is my script for switching audio output devices: https://gist.github.com/omgmog/8c2139c9270431b7cddd93a947c9018c

I'm also now using a cheap 3-key macro pad from Aliexpress (rather than the Pimoroni RGB Keypad as I couldn't think of a good use for the rest of the keys!) that I've got bound to F12/F13/F14 keys.
