Somehow my iPhone Simulator is unable to play sounds. First an app I\'m working on using AudioServicesPlaySystemSound() stopped working.. I spent a while debug
I had no sound in the simulator, so I tested it with mobile safari and tried playing an mp3: No sound!
All the above tips didn't help. Eventually, I changed my INPUT source from the virtual soundflower device to Line-In, and the Simulator worked!
So, even if the app wasn't using input, it didn't work well with Soundflower.
