Using AVCaptureSession to record a video on initialising audio session from a Push To Talk call, audio of the ongoing video recording is getting stopped while the video recording is still ongoing.

We have a Push To Talk application which allow user to record video and audio.

When user is recording a video using AVCaptureSession and receive's an Push To Talk call, from moment the Push To Talk call is received the audio in the video which is being captured is stopped while the video capture is still in progress.

Here after the PTT call is completed, we have tried restarting the audio session, there are no errors that are getting printed but we still don't see the audio getting restarted in video capture.

We have also tried to add a new input for AVCaptureSession we are receiving error that is resulting in video capture stopping, error mentioned below:

[OS-PLT] [CameraManager] Movie file finished with error: Error Domain=AVFoundationErrorDomain Code=-11818 "Recording Stopped" UserInfo={AVErrorRecordingSuccessfullyFinishedKey=true, NSLocalizedDescription=Recording Stopped, NSLocalizedRecoverySuggestion=Stop any other actions using the recording device and try again., AVErrorRecordingFailureDomainKey=1, NSUnderlyingError=0x3026bff60 {Error Domain=NSOSStatusErrorDomain Code=-16414 "(null)"}}, success

We have also raised a Feedback Ticket on same: https://feedbackassistant.apple.com/feedback/16050598
