sounds from any application via AirPlay. Otherwise, you can use the Airfoil software, which has the
added benefit of supporting multiple AirPlay speakers.
Stream audio from your Mac
To use an AirPlay device as your Mac's audio output, make sure your computer is connected to
the same network as the AirPlay device you want to use. You also need to be running OS X 10.8
Mountain Lion to access this feature.
Bear in mind that this method sends all your system audio to the AirPlay device so, unless you
want your party songs interrupted by e-mail alerts, IM messages, or other system sounds, quit as
many apps as possible before you start sharing your music over AirPlay. The benefit of streaming all
your system audio is that you are free to use any app to send audio to your AirPlay device: iTunes for
one song, YouTube for another, and Spotify or Rdio for others.
1. Launch the System Preferences application (click its icon in the Dock or choose Apple > Sys-
tem Preferences).
2. Click the Sound icon in the System Preferences pane to open the Sound system preference.
3. Go to the Output pane.
4. Scroll to the AirPlay device you want (see Figure 3-7). In the Type column next to the selec-
ted device, you should see the word “AirPlay.”
5. Select the device you want to use.
6. Set the output volume and balance using the sliders below the output device list.
7. Close System Preferences.
8. Launch the app to stream audio from, set its volume level if required, and begin playing the
audio you want to stream to your AirPlay speaker.
TIP: You can adjust the Mac's audio volume using the Sound icon in the menu bar. If it doesn't
display, open the Sound system preference and check the Show Volume in Menu Bar option.
