The DMIC needs to have the DMIC ASRC enabled, otherwise capturing audio from it results in mostly capturing noise + the actual recorded voice very soft in the background of the noise.
This has been tested on a Point of View P1006W v1.0 tablet, which is the only RT5651 X86 device using a DMIC that I am aware of.
