The codec need to be muted before the CPU dai has been stopped (McPDM). Stopping the McPDM will generate a pop on the codec since no signal on the PDM bus means full negative amplitude. By managing the mute/unmute state of the outputs we can decrease the amount of pop noise when playback starts or stops.
