; Created so that you can iterate through multiple sound devices on Windows with hotkeys
;
; To make this run automatically when your PC starts, put it (or a shortcut to it) in the Startup folder (For Windows 10: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp)
; 
; Requirements:
; - AutoHotkey
; - nircmd

; Options File
SAVE_OPTIONS := true				; Whether or not to save options to a file after script restart or PC reboot
OPTIONS_PATH = C:\audioDeviceSwapperOptions.ini  ; Path of where to save options if SAVE_OPTIONS is true

; Sound Devices Options
