Videos recording without sound

This seems like a long shot, but has anyone had any issues with videos randomly recording without sound or partially without sound. I’ve been having this issue for a couple of months where my videos will record completely silent or they’ll start out with sound and go silent halfway through. Not the speaker, but the actual video itself is silent. Even if played on a different device. Totally random, could have one video record fine and another taken 60 seconds later have issues. I’ve already exchanged my original phone under warranty thinking it was a phone issue, but just realized today that the issue is still occurring. The only other common thread is that the issue began the day I had google security cameras installed and I have the google home app on my phone. However I’ve disabled access to the camera and microphone for that app and the issue still persists. Is it possible the google home app could be causing this problem? I can’t figure out anything that is causing the issue and everyone I’ve talked to at apple has never heard of an issue like this. It’s so frustrating.
