airplay icon not showing in menu bar
I just upgraded to Mountain Lion, and i have a macbook that should support airplay mirroring. I am trying to send sound to my airport express, and I am able to get everything working if i choose the airport express explicitly in sysprefs/Sound... but when i look at the keynote presenting ML, there should be an airplay icon visible next to the volume control on the menu bar. Is this a setting that i have missed? or is it so that this icon only shows up for Apple TVs and not airplay enabled devices only accepting sound???
It is a real hassle to navigate to sysprefs everytime i want to enjoy some music.
MacBook Pro (15-inch Early 2011), OS X Mountain Lion
