Have you checked the filters for the microphones / speakers? These can get clogged up and require a tiny bit of water and a brush to clean them if they are blocked.

What type of bad sound is it? Is it a clicking sound, a static sound? I have found that if it is a clicking sound, it is often due to the brace between the microphone and the housing on the bottom of the phone not being seated properly

Thank you for your answer. Its a static effervescent noise.

This maybe related to the audio IC on the motherboard. try re-soldering that IC.

I think you’re right, there’s something wrong on the logicboard. Tried with another logicboard and voilà, everything works fine! Had saved many hours and grey hair if I tried this earlier...

Unfortunately I dont do soldering, so I think that logicboard is doomed.
