Question about RX-100

https://www.youtube.com/watch?v=LguzjZkaBo4&feature=youtu.be

A friend of mine ran into an issue with RX-100 and couldn't find a separate subreddit for it. If you look at the video, you'll notice beep sounds coming when recording video.

I've managed to turn off all the sounds within the camera settings and the sound still persists, any idea what can be done to fix it?

Has this issue happened on any other SONY cameras? Thank you for your time!
