Basic UCM configuration for HDA DSP generic enabling codec playback and
capture on both HDA codec and DMIC ports.
Could you describe for what Linux driver (source code) is this
configuration?
This file is for Intel Skylake SST driver. Information added in v2.
Ok, do we have this code in the vanilla linux kernel? Which .c file? The
driver name 'hdadsp' looks suspicious. We usually have a delimiter in the
driver name (like sof-hda-dsp).
+ValueDefaults {
+ PlaybackChannels "2"
+ PlaybackPriority "1"
+ CaptureChannels "2"
+ CapturePriority "2"
+}
Remove PlaybackChannel and Priority defaults. The priorities should be
defined in the device section.
I will check...
Thanks, moved to device section in v2.
+
+SectionDefaults [
+ cdev "hw:hdadsp"
It should be "hw:${CardId}" for ucm2.
Thanks, applied in v2.
+ cset "name='codec0_out mo media0_in mi Switch' 1"
+ cset "name='media0_out mo codec0_in mi Switch' 1"
+ cset "name='mch_cap_out mo mch_cap_in mi Switch' 1"
+]
This file does not define any devices. Does pulseaudio work with this
configuration?
Devices added in v2. Regarding pulseaudio - are there any guidelines on
how to test UCM files with it? These UCM files were writted mainly based
on existing ones for other cards. Of course basic tests were made.
I wrote an ucm validator:
https://github.com/alsa-project/alsa-tests/tree/master/python/ucm-validator
Just type 'make' in the ucm-validator directory, the alsa-info.sh output
should be added to the configs subtree.
The PA should be used latest from gitlab with the volume control and HDMI support.

Thanks,
