We recently up streamed ACP PDM driver for Renoir APU.
Our ACP IP has an internal PDM Decoder block where DMIC is directly
connected.
There are no KControls defined for PDM Driver.
Our platform supports on board DMIC and South bridge Azalia (HD Audio
) endpoint .
By default, DMIC endpoint is used as audio input device.
When Headset Mic jack connected, it's not switching to External Mic.
Make sure that the Headset Mic priority port in pulseaudio is is
greater than the one for DMIC.
How does audio endpoint will switch in gnome when external mic is
connected?
From our understanding, UCM conf file for HDA driver is also
required for
configuring mixer controls for HD Audio capture device.
Similarly when External Mic is removed , it has to switch to internal
dmic .
An configuration example for UCM (DMIC connected to DSP, HDA codec for
rest):

If you need a help to create a new configuration for your hardware,
show the output from the alsa-info.sh script, please.

This audio design is a bit different from sof-hda-dsp, the dmic is on a
standalone sound card. Please see the alsa-info.txt:
