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 Ubuntu Bugs, which is subscribed to 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1845677/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
