The problem began after the last updating or the one before. I've turned the recording mode to "Manual", and when I start a moment record(set to 60 seconds) this file has no sound. Sometimes turn to Auto and it goes alright but the problem is that I don't know when my video is going to have sound or not.
Might be having some issues with initializing the audio device. I'd recommend creating a ticket with logs attached so we can see if that's the case. Here is how to send that in: LINK
