FP4 Microphone not working on loud speaker on GSM calls

Call quality and noise cancellation (regular calls, handsfree, Signal voice messages, Microsoft Teams video calls)

Yes. Mic 1 (the bottom one) works fine. Mic 2 and 3 do not provide any feedback. I was trying to tap on all of them, but all I can hear is silence. But as I said, using the video recording and loud calls, I can in fact confirm they’re working and the volume is roughly the same for all of them. So the main issue is the tests behave weirdly and that audio gain in general is too low to my taste (especially in video and audio recording, calls are acceptable).
