A7S iii Audio Issues Please Help.

[lostmentality]

Hello my name is josh i purchased an A7S iii almost a year ago. i freaking love the camera. I've started to notice a little bit of a audible click coming from my external mic. so to diagnose. I used a separate external mic with the same audio cable and a different mic with a different trrs cable. I isolated that nothing fixed the issue. So i was with firmware 2.0 updated to firmware 2.01 no change. please listen to the audio in this video and please advise only way i can think to explain the issue

I realized the audio was trash as i was editing the video. needing to put out content I went ahead and posted it. please advise if anyone has had experience with this issue.
