Tools: Topology2: Add pre-processing to ACE3.x PCM DMIC topologies
The topologies for PCs those have PCH DMIC enabled have too silent noteboook lid microphones capture level. It can be improved with enable of DRC and beamformer TDFB components in topologies build. Since the same pipelines are not used for other microphone endpoints, it is safe to apply fixed processing configuration. The topologies with -2ch are set with DRC profile "dmic_default" and with TDFB profile "line2_generic_pm10deg". It provides about +10 dB boost to sound level and a user facing microphone stereo beam that improves signal-to-noise ratio. The user space controls are disabled by default, so the user needs to set the features on with alsamixer or amixer conmmands. The 4ch topologies are set with passthrough blob for beamformer. With a lot of variation in array form factors there is no generic setting available. The DRC setting is the same for 4ch and provides +10 dB boost. The impacted topologies are: - sof-ptl-rt722-4ch Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>
