Fast input/output sound device switch for OSX
I you have an USB headphone,used on a laptop, you end up having to switch back to your USB headphone after reconnecting your headphone. This is king of annoying since you have to go in the preference/sound panel to do the operation.
I found SoundSource from RogueAmoeba. It's really cool, install in your Apple bar and let you switch with a single click :
SoundSource is a tiny tool for OS X enabling you to switch your audio input and output sources with a single click. And with the System setting, you can transfer system beeps to a secondary audio source so you won't be disturbed.
Highly recommended small application.
