Quickly changing sound output
Q I have just upgraded from Mountain Lion to Yosemite. I have also just purchased a pair of USB headphones, but have to adjust the sound input and output settings each time. Is there a script or app that would allow me to alter these settings simply with less key clicks from either the menu bar or perhaps a defined hotkey? Perhaps I’m being too lazy. Christian Webb A The long way is to open System Preferences > Sound and set the input device to your headphones. Holding å and pressing any of the audio function keys in the top row of an Apple keyboard will take you directly to these preferences. You can shave off another few seconds by å- clicking the volume icon on the menu bar. The menu will then show all the available audio inputs and outputs for you to choose from.
