Bad microphone audio during calls (handfree is working)

Hi guys!

since some days I'm experimenting problems in microphone audio during calls (latest lineageOs installed). Using handfree the other peoples hear me like ever (and it works when register audio, whataspp audio message but not calls), switching back to headset, the other people hear me very very far and diturbed; so it seems not an hw issue.

This happened some years ago (and I temporarly fixed it same way).. but there's someone that know why it happen (and then how to fix it)?
