I use the digital audio out from my PC to play music/movies/games through a home theatre. The "Room Correction" audio enhancement optimizes sound for when I'm seated at my computer and it works great. If I want to sit on the couch (in the same room, watching a source off the computer using my TV) then I turn the Room Correction off by "disable all audio enhancements" in the audio menu. I found that only
disabling "Room Correction" resulted in it losing my measurements, so Disable All is what I want.
Since I do this a lot, I would like to set up a hotkey to enable/disable all audio enhancements without having to go through the menus.
