Main microphone is broken (mic1)

Hey guys.

I might be in a bad streak.

1. I broke my pixel 8 pro screen last month
2. I bought a replacement from Ifixit around two or three weeks ago, installed it and it worked perfectly.
3. Two days ago, though, I lost my main microphone. I already tested the hardware with the self test and mic1 doesn't record anything :( . Mic2 and mic3 do work.
4. I guess I can also replace it, but I haven't found the part anywhere
5. Question: Is that doable? Should I test something else before buying the part?

Thanks!!!
