- AutoHotKey (has to be installed)
- based on: http://hackerspace.kinja.com/switch-between-two-audio-devices-with-autohotkey-1687823820
- uses Vista Audio Control Functions (works for Vista and later)
- Icons are from headset and speaker
- Ctrl+Alt+F11: Switch between playback devices
- Ctrl+Alt+Page Up: Volume Up
- Ctrl+Alt+Page Down: Volume Down
Shortcuts can be changed and extended inside script (AudioShortcuts.ahk)
Does not use "Run, mmsys.cpl", therefore it does not open a window
