Thanks @Hui, @Shengyao Using 5.3.0-21-generic from proposed, the ucm config files (via ppa:xueshengyao/dmic), and blacklisting snd_hda_intel and snd_soc_skl, both speaker and HDMI audio out work. (related: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848490)
Apologies if this is off topic for this bug report, but after the installation of oem-dmic-sof-lp1825294, it seems that audio HDMI / DisplayPort audio sinks (such as those connected to a dock) are no longer discovered. I'm not familiar with how everything is in play here, so if more information is necessary, please just let me know if gathering more information would be helpful. ** Attachment added: "dmsg-after-oem-dmic-sof-lp1825294lsp.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1845677/+attachment/5304532/+files/dmsg-after-oem-dmic-sof-lp1825294lsp.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1845677 Title: volume control doesn't work (it's just on/off) on Lenovo ThinkPad X1 Carbon 7th gen Status in linux package in Ubuntu: Confirmed Bug description: On my Lenovo ThinkPad X1 Carbon 7th generation using the built-in speakers, the volume is either off or on, there's no gradation in volume when I move the slider up or down. If I enable Over-Amplification than there's gradation in volume when I turn the volume up past 100%, but not for 0-100%. This problem does not occur with a headset plugged into the 3.5mm jack.
