avc = [[MPAVController sharedInstance] avController];
//avc is AVController
NSString *path = [[NSBundle mainBundle] pathForResource:@"Sound" ofType:@"wav"];
id feeder = [[MPArrayQueueFeeder alloc] initWithPaths:[NSArray arrayWithObject:path]];
    	[avc setQueueFeeder:feeder];
    	[avc play:nil];

    	[feeder release];
