Today, after messing around with saving highscores, suddenly my application will not run at all.
I get the following message in the log:

2011-07-25 20:09:46.622 Hover[1217:207] Denshion::CDAudioManager - Audio session set category
 AVAudioSessionCategorySoloAmbient failed with error Error Domain=NSOSStatusErrorDomain Code=-50
"The operation couldn’t be completed. (OSStatus error -50.)"
2011-07-25 20:09:46.624 Hover[1217:207] Denshion::CDSoundEngine - mixer output rate set to 44100.00
AudioStreamBasicDescription:  2 ch,  44100 Hz, 'lpcm' (0x00000C2C) 8.24-bit little-endian signed integer, deinterleaved

Seams like some kind of problem with the audio, which is weird as I haven't made any changes to the music.

Help?

Nevermind, I think it fixed itself, at least for now!

I thinked I messed around with commenting out recent parts of my project than building it, but nothing seemed to help, so I just gave up and went to sleep. The next day it worked, no idea why, sorry.

Cocosdenshion people: have you had the same issue before? It started to happen to me after an update to Lion, and it happens on both simulator and device.

I've noticed it on mine as well. Not sure if it's after I upgrade to Lion or not, but it has been recently, so it's a high probability.

As an additional issue: When you get the -50 error code, CocosDenshion continues trying to initialize the sound which brings an exception later making it tough to debug using the emulator. The only workaround I found was to run with breakpoints disabled. @Steve-Oldmeadow: how you seen is issue before
?

@Diego R - no I haven't seen it. How about some details e.g what version of CocosDenshion, what devices, what firmware.

Latest CocosDenshion/Cocos2D (1.0.1) from develop branch. IOS 4.3.5 iPhone 4.

@Diego R - I have no problems with that configuration. I suggest you follow standard troubleshooting practices as outlined in the FAQ. e.g run some of the CocosDenshion example projects and see if you get the error there.

It could be Lion related but I would have thought we would have lots more people reporting issues if that was the case. I don't really understand why the OS would make a difference on the device. The only thing that I can think of is a different compiler in XCode 4.1 - so maybe try a different compiler like gcc. I don't anticipate upgrading to Lion for months as I am waiting for upgrades to lots of software that doesn't run correctly on Lion/XCode 4.1 yet.

I am having the same problem.

OS X Lion, XCode4.1, cocos2d 1.0.1

when run simulator & device, console log is ...

How can I fix this?

Thanks in advance.

@nybounce - did you read what I said to Diego R.? Try some CocosDenshion demos, if they don't work then it is a general issue. Try a different compiler. It seems to only effect Lion users so unless you give me more details there's not a lot I can do. As I said before, I'm not upgrading to Lion until all my software will work on it.

I created new project. then test SimpleAudioEngine.

-(id) init 

[[SimpleAudioEngine sharedEngine] preloadEffect:@"1.mp3"];

-(void)ccTouchesBegan

[[SimpleAudioEngine sharedEngine] playEffect:@"1.mp3"];

-(void) dealloc

[SimpleAudioEngine sharedEngine] unloadEffect:@"1.mp3"];
