When your Galaxy S20 Plus loses sound

The micro daughter card of the Galaxy S20 Plus manages all audio capture and playback on your device. Failing microphone, sound cutting out during calls, voice recognition no longer working, inaudible internal speaker: these failures point to this part. If you can still hear your contacts but the microphone doesn't detect you, or vice versa, the problem comes from right here. Once replaced, voice becomes clear on both transmission and reception, voice assistants regain their effectiveness, and audio recording works again.
