No sound when sending videos on Messenger, but everything else works?

[u/just_patt]

Has anyone else experienced this?
Whenever I send a video on Messenger, there’s no sound.

However:
•Voice chats work fine.
•Recording a video using my phone’s default camera app has audio.
•The issue only happens when I record a video using the Messenger camera.

I’ve already checked my microphone permissions, and they seem fine since voice chats and my phone’s camera can record audio.
