Volume automatically de- and increasing

Hi!
I’ve got the exact same problem as described in this closed thread : Speaker gets low during quiet audio, then "wakes" up during loud audio Imho it’s an annoying problem that’s affecting audio experience a lot, so I’m reopening the discussion. Hope that’s according to the community rules.

Does anyone have a clue about where this might come from? My random guess would be that it’s some kind of adaptive volume feature that should increase the phone’s volume whenever surrounding noise goes up and vice versa, but it’s mastakenly considering the phone’s own audio output as noise and thus getting louder, when the music plays a bit louder, and lowering during more quiet parts…

Or any clue how to switch this off?

My phone is a FairPhone 3, build 8901.3.A.0134.20211116. Have been experiencing this ever since I bought the phone.

Thanks for any help!
