PlayEventSound fine in sim, fine on iPad, none on iPhone

I cannot get any sounds to play on my iPhone app when calling playEventSound. However, the exact same build (universal) works fine on the iPad and also in the simulator.

Background music is also fine on all devices using PlaySound - it’s just PlayEventSound that doesn’t work on the iPhone!

Audio files are .caf, iPhone is 3GS.

Any suggestions?

OK, it’s working now - I closed all other apps on the phone and now it’s fine.

I think TuneIn Radio may have been the culprit.
