@Paolo, The kernel you installed is too old, we integrated Intel's kernel patch to switch to use snd-hda-codec-hdmi instead of soc/codecs/hdac_hdmi.c.
Please update your kernel to Ubuntu-5.3.0-40.32 then redo the test. And please don't install Ubuntu-5.3.0-41.33, there is some regression in the -41 kernel. And all these issues will be addressed in the -42 kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859754 Title: add ucm to make alsa/sof driver work under PA (variants of Lenovo X1 Carbon 7th, Dell cnl and cml machines) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1859754/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
