RE: iPhone limit audio playback to speakers

Just to add to this:
Before initializing openal I configure an AVAudioSession object to not play sounds from the iphone's headphone jack, however openal seems to ignore this setting.
// setup audio session
NSError *error = nil;
AVAudioSession *session = [AVAudioSession sharedInstance];
[session setCategory:AVAudioSessionCategoryPlayAndRecord error:&error];
NSAssert(error == nil, @"Failed to set audio session category.");
	
// Make sure the sounds don't play out the headphone jack 
OSStatus propertySetError = 0;
UInt32 doChangeDefaultRoute = true;        
propertySetError = AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryDefaultToSpeaker, sizeof(doChangeDefaultRoute), &doChangeDefaultRoute);
NSAssert(propertySetError == 0, @"Failed to set audio session property: OverrideCategoryDefaultToSpeaker");

Neither of those NSAsserts fire.
The iphone dev website says to direct openal questions to this forum.Anyone have experience with this?thanks,Chris
