[UCM] Enable DMIC input device for generic HD-A machine #855
Description
PulseAudio can detect input/output devices in 2 ways:
- Check amixers with standard names defined in /user/share/pulseaudio/alsa-mixer/paths ... for legacy HD-A driver;
- check playback/capture devices defined by UCM for a sound card ... for ASoC drivers
Current open:
SOF reuse the legacy analog codec drivers which exposed standard amixers for speaker and headset, and can be recognized by PA in way#1. But SOF support HDMI output devices and DMIC suppported in ASoC style but w/o UCM file.
It seems we need to write SOF UCM file for generic topology to cover speaker, headset, DMIC and HDMI.
Describe the bug
Wrong device list for sound input and output on CML and WHL platform.
To Reproduce
Check Settings->sound->Output/Input on ubuntu.
Screenshot:
Expected behavior
1.Outout and input hould not list Mutichannel device
2.Input device can not find DMIC device

Release alpha version of UCM. Next I will refine the UCM and machine driver to upstream it.

Closing as fixed by adding UCM

@RanderWang Please help to upstream UCM to alsa-lib.
