No sound after re-entering app (multitasking)

[Smash22]

Hey everyone - it seems like whenever I navigate out of my game and return to it no sound effects can be heard, however the music still plays. I have only been able to test this on the simulator as I have an iphone 2g. I am using openAL by the way.

Just wondering if anyone has any idea why this would be happening. Thanks

You probably need to restart your audio session after returning, either with AVAudioSession or with the C API.

With OpenAL you need to set up your OpenAL context again.
