If you can’t play a song purchased from the iTunes Store: You may have exceeded the number of computers on which you can play your purchases. If you’re using an AirPort Express, you can find more troubleshooting information in the documentation that came with your AirPort Express, or at the AirPort Support website. If you’re trying to listen to music through remote speakers using AirPort Express: Make sure the remote speakers are selected in the AirPlay pop-up menu at the top of the iTunes window, and the volume control on the speakers isn’t turned down. Also make sure their volume isn’t turned down.

If you’re using powered speakers connected to your computer: Make sure the powered speakers are properly plugged into your computer’s audio port, plugged into a power source, and turned on. Also, try playing a different audio file, CD, or DVD, or try playing the file or disc on another computer or media player to isolate the problem. Check the control at the top of the iTunes window and check the computer’s output volume (in the Sound and Audio Devices Properties control panel). If you’re using your computer’s built-in speakers: Make sure the volume controls are not turned down.
