IPhone (SDK 2.2): Adusting Playback Volume While NOT Actively Playing Music W/ AVFoundation?
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 playback.
When a sound is actively playing, and the user uses the hardware volume buttons, the playback volume changes. Problem is, the app is NOT constantly playing sounds, and when it's not, and the hardware buttons are used, the RINGER volume gets adjusted instead.
How do I set it up so, as long as the app is running, the user can adjust the playback volume?
Thanks!

Answer
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.
