Audio from iOS is muted after having responds from siri.

User cannot hear sound after siri's respond when playing the app.

When user go home screen then back to the app, then the user can hear the sound.

This is related to [Link Removed] but this ticket is marked as resolved and wants to give simpler repro step, I created this ticket.

1) Create a new project based on First person template

2) Deploy it onto device (iPhone X for example)

3) Touch the screen to check the fire sound

4) Open up siri(by calling or pressing side button corresponding the device's settings)

5) Ask something that siri will respond (tell me some funny stories)

6) After siri responds with audio, go back to the app and press the screen

Expected: User can listen fire sound

Result: No sound. (No audio)
