Hello all,

i have two laptops with internal dmic, each of them has 3 step mic
boost. One step 12 dB. The third step seems to me useless, since it give
more noise then sound.
I know there is code in patch_reatek.c to disable two steps.
But before i provide some patch, it will be interesting to know, how
much noise is too much? What is the best way to measure it?
Do i need some tools like this?
