** Description changed: 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://github.com/thesofproject/alsa-ucm-conf.git + + [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-setting, both output and input devices work well. + + [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.
