Can you start with a soft reboot by turning your phone Off and On @andybeach
Please also look in any relevant sound settings in the phone if you haven't already done so.
May I assume the sound is working on normal speed video's ?
And on calls etc.

The advice I offer is my own and does not represent Samsung’s position.
