FreeAudio sometimes failing on OSX10.5

Has anyone ever had a problem where FreeAudio sometimes stops working on OSX10.5?

I've got a customer who is able to play the game for a couple of hours and then the sound stops and when he restarts the game SetAudioDriver(FreeAudio) must be failing because I have some code that writes SOUND DRIVER=None in the ini file if it fails.

No, I haven't that problem - my program has been playing music and sound effects fine at each run.

OK thanks. I've only heard of one customer with this issue out of thousands so maybe it's not a big deal. Weird though...

Maybe just a suggestion, but has the customer tried running the game under a newly created user account?

In a new user account you are sure that all OS settings are default. If it runs under that account perfectly it may be something that starts up automaticly after logging into the user account that is in conflict or a setting somewhere in system preferences that is not default anymore.
