Sound Issues with iOS 11 (latest update 2017-10-31)
Four or five users have reported a clicking or crackling sound during the play of mySleepButton. This issue started happening when iOS 11 was released, and only affects iOS 11 users. There are several reports that iOS 11 introduced such errors. One user sent us recordings of this sound. We compared it with our own recordings and found a difference. This means that the issue is not with mySleepButton. It seems to be an iOS issue. Apple has in fact issued several minor releases to address sound issues, the latest minor release being 11.0.3. This has alleviated some of the sound issues reported on with iOS 11 for other apps. But some of our users still report problems.
Apple has just today released iOS 11.1. We had heard that this was supposed to address sound issues, but we cannot yet confirm whether it has.
