I'm having (another) strange audio problem. I'm using SimpleAudioEngine to play a looped background music during game play. When a user toggles the "pause" button, the sound stops. It is supposed to resume playing when the game starts back up. I don't know what I changed recently, but it used to work. Now, the background music plays the first time, but never resumes after it's paused. Here's what I'm doing:
- (void) init {
// normal init stuff
if (myGame.soundFxEnabled) { // myGame refernces my game data class
SimpleAudioEngine *sae = [SimpleAudioEngine sharedEngine];
if (sae != nil) {
[sae preloadBackgroundMusic:@"bgmusic.caf"];
if (sae.willPlayBackgroundMusic) {
sae.backgroundMusicVolume = myGame.soundFxVolume;
}
}
}
- (void) togglePower:(id)sender {
if (toggleOn != YES) {
[power selected];
toggleOn = YES;
gameClockTimer = [[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(updateGameClock) userInfo:nil repeats:YES] retain];
if (myGame.soundFxEnabled) {
[[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"bgmusic.caf"];
}
} else {
[power unselected];
toggleOn = NO;
[gameClockTimer invalidate];
if (myGame.soundFxEnabled) {
[[SimpleAudioEngine sharedEngine] pauseBackgroundMusic];
}
}Seems pretty straightforward, and it was working for me until recently. I don't know what changed. Here's some of the Denshion related messages in the console:
// pre-loading stuff from init
// the other sounds are coming from another layer's init
Denshion: Checking for other audio

// but the audio does stop correctly
// switch turned back on
// calls the same request, but nothing plays
Denshion: request to play current background music fileThis happens in the Simulator and on the device (both running 3.1). I'm using cocos2d 0.8.1 with the CocosDenshion files from 0.8.2
Is there a retain I'm missing somewhere, or is there something I'm doing wrong?
