Very low microphone on 2 Xperia 10 III

I had only phone one and microphone was very low. So I ordered new microphone and it did not help. Replaced the flexicable to a new one too, no succes. Got back my other 10 III with jolla installed too and reinstalled it to realise it too have very low microphone.
Microphone works with video recorder but not with audio recorder or calls. With help from Chatgpt I managed to get it working with audio recorder, but not with calls. Mic works but I have to yell for decent voice in the other end?

I hoped that latest update would fix this but no, it did not.

Any hints?
