MacBook Air M1 mic volume decreases automatically

Hello, I have a MacBook Air M1. Each time I increase the sound input volume (Mic), after a while it decreases by itself, maybe after a day or two or even a half day. Whenever I notice that the volume has gone down, I have to raise it again, and this keeps happening, which is very annoying. Maybe the apps I’m running are adjusting the volume automatically, but I think I need a solution for this.

A mic for what(?)

Is there some particular app involved/ third party app(?)... hard to say more for a lack of any detail.


A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies


Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled temporarily.


Login and test. Reboot as normal and test. Caches get rebuilt automatically.
