This patch replaces the default 0 dB gain with +20 dB gain in 16 kHz DMIC pipelines in hda-generic based topologies. It is done to have same capture sensitivity in both 16 kHz and 48 kHz capture pipelines. The impacted topologies are: sof-hda-generic-2ch.tplg sof-hda-generic-4ch.tplg sof-hda-generic-eq-2ch.tplg sof-hda-generic-eq-4ch.tplg sof-hda-generic-idisp-2ch.tplg sof-hda-generic-idisp-4ch.tplg Note: The 0 dB high-pass version is preferred after all the needed development is available.
