Therefore both digital microphone data channels must be enabled also when using mono microphone configuration. Fix this by moving "DMICL_ENA" and "DMICR_ENA" supply widgets from "DMICL" and "DMICR" inputs to "DMIC Mux" in order to enable both data channels whenever there is active mono or stereo digital microphone input path. Use of "DMICL" and "DMICR" inputs are retained for informative source and in case the driver would find use for exact digital microphone configuration in the future.
