I'm running 5.4.0-18 from focal-proposed and have installed the sof firmware from this pull request:
https://lists.ubuntu.com/archives/kernel-team/2020-March/108035.html With this it looks like the sof driver is being used. Speaker output works, though the volume seems very low (which has always been the case under Linux on this laptop, so maybe that's normal?). The only input device listed is sof-hda-dsp, which does not appear to be picking up any sound. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1860697 Title: Sound doesn't work on Lenovo X1 Carbon 7th with 20.04 Status in linux package in Ubuntu: Confirmed Status in linux-firmware package in Ubuntu: Confirmed Bug description: I recently upgraded from 18.04+HWE kernel to 20.04 and now sound, both output and input, does not work.
