iPhone 4 sound issue

Have a couple of reports of sound not working correctly on iPhone 4. Trying to get hands on one for testing. App works on 3gs and iPad with no problems. Trying to figure out in the mean time how this could happen. Has anyone had any issues with iPhone 4 acting differently with sounds?

What version of iOS are these devices running?

There have been some forum posts about sound problems with iOS 5. [import]uid: 67839 topic_id: 17152 reply_id: 64547[/import]

Yeah, If they’re using iOS5 there’s an issue that was fixed with build 2011.645
