iPhone (SDK 2.2): adusting playback volume while NOT actively playing music w/ AVFoundation?

Question

So I have an app which plays many short sound clips. I need to know when the sounds are finished playing, and I need to use mp3s, so I\'m using AVFoundation for the sound playb

Answer 1

Turns out this can be accomplished by allocating an AVAudioPlayer with any valid sound file and calling the prepareToPlay method, without ever calling the play method.

Works perfectly.

Answer 2

so you want to disable ringer playback volume as long as the app is running? therefore the hardware controls will only adjust the app playback sounds?

i dont think this is possible unless you are "always playing sound" for example, many games are always playing background music or what have you.

Answer 3

You might be able to accomplish this by constantly playing a 0 volume sound as long as your app is running. You could then play your sound clips over it.

• How do I play multiple sounds simultaneously?

Answer 4

Start an AudioSession and don't stop it when you're not playing sounds.
