How to change Sound device without visiting System Preferences? Are there any alternative ways to switch your Input/Output sound device in OS X?  My goal is to avoid going through System Preferences and have as few keystrokes/steps as possible.
To enable the sound icon on the top menu bar, only once you have to go to System Preferences-> Sound-> Show volume in menu bar

alt/option + click on the Sound icon on the menu bar to get this dropdown and select the desired output or input device
