Bug Description
This ucm is only for Eoan and Bionic, for focal and future versions, we plan to integrate the ucm2 instead of this ucm, and the ucm2 depends on the alsa-lib-1.2.1 and pluseaudio-v14, the ucm2 is under developing by the community, is not ready yet.
[Impact]
In the oem project, we have a couple of Lenovo and Dell machines which
connect the digital mic to PCH directly, this design needs the new
sound driver soc/sof, and this driver can't work under pulseaudio
automatically, we need to integrate the ucm for the driver, then the
sof dirver could work under pulseaudio and gnome.
This ucm is maintained by intel audio team, and it is not upstreamed
and will not be upstreamed, since the community is developing the ucm2
which is based on at least alsa-lib-1.2.1 and pulseaudio-v14.0 (still
under developing), for bionic and eoan, we have to integrate this ucm
since the alsa-lib version is too low. For focal and future version, we
are going to integrate the ucm2 after the ucm2 is ready.
This ucm is already verified in the oem project, now it is time to put it
into the stock ubuntu.
[Fix]
These ucm files are backported from sof_ucm1 branch of
https:/
[Test Case]
Boot the eoan kernel or oem-osp1-bionic kernel, then check the log of
pulseaudio, the ucm files are loaded successfully, then check the
gnome-sound-
[Regression Risk]
Low, just add some new ucm files, and this will not affect other machines,
and those new added ucm files are only used by specific machines which enable
the sof driver.
