Have a few S3 P

Have a few S3 Pro cameras that audio stopped working. I can sound the alarm. I can hear audio while watching live video. As soon as I go to talk through the camera though, nothing. No sound on either end. Anyone else having the same issue?

I have a few that now like that as well

Have you tried restarting the device / camera?

Strange

I’ve restarted a few times but the issue is not resolved
