Any idea on how to make the microphone work properly?

I've been playing Warioware Gold on my Galaxy A36 recently; and outside of the frame rate slowing a bit in some microgames, it works like wonder.

However, the microphone options seem to be really not that helpful. Real (Cubeb) doesn't registers anything and Real (Open Al) is like an automatic one.
