the data folder has subfolders where the image and sounds are kept

as I was saying above, it’s trying to load by using a vector of strings passed in when needed using a stringtToNSString function, as I’m mostly writing in c++

[NSString alloc] init:@”sound.wav”];
this does not work if the file is “Sound.wav”

Correction:
[NSString alloc] init:@”Sound.wav”];

I don’t think it is the problem, but just had to type it!

Hi
I’ve been enjoying using soundManager to load sounds into a comic I’m making but I’ve hit an issue. I have an error after the sixth file tries to load. I am calling the contents of a directory, names of files, and passing them in as strings converted to NSStrings (I should add I am writing using openFrameworks http://www.openframeworks.cc) in which most of my code is c++ and into which I am dropping handling sound.
So my idea is:
a vector of strings..
vector justSounds;

and in my main code, to load and play a first sound:
for (int i = 0; i= 40-radius && touch.x = 430-radius && touch.y <= 430+radius){

currentImage++;

currentImage %= nImages;

images[0].clear();
images[0].loadImage(IMG.getPath(currentImage));

[sharedSoundManager removeSoundWithKey:stringToNSString(justSounds[currentSound])];

currentSound++;

cout << SOUND.getName(currentSound) << " sound name value\n";

[sharedSoundManager loadSoundWithKey:stringToNSString(justSounds[currentSound]) musicFile:stringToNSString(justSounds[currentSound])];

[sharedSoundManager playSoundWithKey:stringToNSString(justSounds[currentSound]) gain:1.0f pitch:1.0f location:CGPointMake(0, 0) shouldLoop:NO sourceID:-1];

This is where the console shows the first few sounds appearing to load and play fine (and they do in the simulator) I hit the crash at image 6, and I don't understand what I'm doing wrong

I get weird errors when I try to add the classes to an empty project. I added all the required frameworks (OpenAL, AudioToolbox, CoreAudio) but I get errors like these:

“_AVAudioSessionCategorySoloAmbient”, referenced from:
_AVAudioSessionCategorySoloAmbient$non_lazy_ptr in SoundManager.o

“_OBJC_CLASS_$_AVAudioSession”, referenced from:
objc-class-ref-to-AVAudioSession in SoundManager.o

“_AVAudioSessionCategoryAmbient”, referenced from:
_AVAudioSessionCategoryAmbient$non_lazy_ptr in SoundManager.o

I really don’t understand what’s going on. Haha sorry for disturbing you… I’m not even able to create a new project correctly. xD

Anyways, I guess I’ll try to figure it out later. Thank you very much for your help. Very appreciated.

I used the latest iOS 4.0 GM Seed (well there is only one). The funny story is that when I changed the soundmanager class from V3 to V4, I did not had it changed properly, because the files were referring towards an other directory.

But hey, try starting a new openGL project, add the classes (just download them again from Mike’s comment to be sure) and let it work in the new xcode project. I gave it a try yesterday evening and everything worked well in a new project.

Goodluck!

Thanks for responding. Do you have iOS4 on (one of) those devices? I had no problem with previous versions of the iPhone OS either… I just found the cause of the leaks: it’s one line, in the initOpenAL method: alcMakeContextCurrent(context). When I comment it out, I get no leaks at all on the device, but the sounds won’t play, obviously (the music does, though). I really don’t know why it’s causing leaks, so I have no idea how to fix it. :S

I keep my fingers crossed, but so far testing my app on my iPhone, iPod Touch and iPad gives me no leaks on the soundmanager class, or anything sound related.

Good luck!
