this my code: iOS14 iOS15 This is working correctly in all iOS 14.x, but on iOS 15.0 seems broken. Thanks a lot for any tip or help.

`try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playAndRecord) try AVAudioSession.sharedInstance().overrideOutputAudioPort(.speaker) That doesn't work. The background music still comes from the headphones.
