Sound not working in iPhone Simulator?

Somehow my iPhone Simulator is unable to play sounds. First an app I'm working on using AudioServicesPlaySystemSound() stopped working.. I spent a while debugging this but sound is still working on the iPhone when I run the app on the device. I get the same results with other iPhone apps such as the sample Crash Landing app.

I can't find a sound setting anywhere in the simulator or Xcode preferences. I've tried resetting the simulator through "Reset Content and Settings" menu item to no avail.

On your Mac, go to System Preferences > Sound > Sound Effects and then uncheck and recheck "Play user interface sound effects".

You need to re-activate your system sounds, see the end of this page.

I've found sound to be very inconsistent in the simulator (2.1 SDK). Sometimes it works, sometimes it doesn't. Even when it does work, it's usually very choppy and distorted (when playing audio files such as mp3).

A few things to remember:

  • call AudioSessionInitialize as soon as your app finishes launching
  • set the kAudioSessionProperty_AudioCategory property for the session via AudioSessionSetProperty (with a value such as kAudioSessionCategory_MediaPlayback)
  • call AudioSessionSetActive(YES)

Of course when all else fails, just run it on your hardware!

EDIT: Now that the 2.2 SDK has been released, I haven't had any problems with sound in the simulator. They must have fixed the bugs! I highly recommend you upgrade to the 2.2 SDK.

OpenAL not working on the simulator was fixed with the 2.1 SDK. Make sure Active SDK and Active Executable are set to 2.1.

By the way, make sure you're using the last version of CrashLanding (v1.8). Some nasty leaks in SoundEngine were fixed recently.
