iphone: (audio) posting message to kill mediaserve

问题:

I'm playing several sounds using: AudioServices

AudioServicesPlaySystemSound(aSystemSoundID);

When I test the project on an iPhone 3G attached to the machine I get this message:

> 2010-09-16 17:29:29.672

and / or:

> Error: AudioQueueNewInput failed
> (0x10004003)

Any idea why?

Thanks.

BTW, on the simulator everything works fine.

I noticed this post, which sounds sort of similar. Is trying this an option?

AudioQueueStart posting message to kill mediaserverd

I was getting the same message when trying to set the audio category (I'm using Audio Units). A reboot of the iPad fixed it for me.
