Exactly what I needed!
I have a very simple need. I have two Thunderbolt displays side-by-side. I wanted to be able to play audio through both displays AND be able to control the volume from the keyboard. AudioSwitcher had me configured and running in less than a minute. As an added benefit I can easily set the volume for each display. This allows me to compensate for the partial deafness in my right ear. I look forward to exploring the abundant options available. Well worth the $0.99!
