Ios simulator cannot find resource file in avTouch sample app.

Question

Hi. I am trying to run the sample project avTouch in the iOS Simulator, and it cannot find the sound resource file sample. It compiles OK, launches, and when I click the Play button, it gives these errors in the iOS Simulator:
2011-08-28 14:16:17.454 avTouch[962:6c03] Error '!dat' trying to set the (null) audio devices' sample rate
2011-08-28 14:16:31.057 avTouch[962:207] Could not play file://localhost/Users/jonesbb/Library/Application%20Support/iPhone%20Simulator /4.3.2/Applications/20290DEF-8855-41E2-92D5-6CF06D6D58F4/avTouch.app/sample.m4a
The file does exist at that location, and I can open it and play it in QuickTime.  I wonder if the path to that location may be the problem.  Is it supposed to use "%20" instead of spaces in the path?  Does the system resolve them into spaces?
I am using MacOS 10.6.8 on a MacBook Pro, XCode 4.0.2, and compiling for iPhone 4.3 simulator.
I've programmed a long time in other IDEs, but I'm new to XCode and all the libraries, so I'm probably missing something obvious here.  Any suggestions will be greatly appreciated.

Additional info.  The app runs and displays the name of the sound file, and also displays the duration of the sound, so I think it is loading the file OK.  It gives the problem when I hit play.  I have a break point in this method, at [p play] below, and it gives the first error at that point.  The second error message is just reporting the result of the first error:
-(void)startPlaybackForPlayer:(AVAudioPlayer*)p
    if ([p play])
        [self updateViewForPlayerState:p];
    else
        NSLog(@"Could not play %@\n", p.url);
