I believe that this bug for 21.04 is the same as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1924685 and the root cause is the misconfiguration of kernel flags.

I installed Ubuntu 20.04 LTS fresh, sounds did not work on speakers or 3.5mm headphones, using linux-image-5.4.0-42-generic, I did not try blutooth. I sudo apt upgrade, dist-upgrade to get kernels linux-image-5.8.0-38-generic linux-image-5.8.0-40-generic Sounds did not work. I download linux-image-unsigned-5.10.9-051009-generic. Sounds did not work. I upgrade Dell XPS 9700 firmware from 1.3 to 1.63. Sounds did not work. After googling I found this solution in the comments: https://askubuntu.com/questions/1270442/no-sound-on-xps-17-9700 """ Download and install dkms module: https://launchpad.net/~canonical-hwe-team/+archive/ubuntu/pc-oem- dkms/+packages Alternatively, you can install linux-oem-20.04, it will install the 5.6 kernel with the above driver. Your system may be more stable with 5.4 kernel since it is in wide use. Manually install sof-firmware from Arch Linux: https://archlinux.pkgs.org/rolling/archlinux-extra-x86_64/sof- firmware-1.5.1-1-any.pkg.tar.zst.html You will need to delete the existing "sof" and "sof-tplg" files from the Ubuntu linux-firmware package first. Note if this package gets updated from Canoncial and they don't update these, you will have to delete and then reextract. Files go into the /usr/lib/firmware/intel/sof and /usr/lib/firmware/intel/sof-tplg folders. Manually install the ucm2 files: http://xps17.ddns.net/sof-soundwire.zip These go into /usr/share/alsa/ucm2/sof-soundwire. Delete the contents of the existing sof-soundwire folder (if you have it) and replace them with the ones from the archive. Reboot. You should now have all your audio devices available. If speakers do not play, you may need to run alsamixer (non-root) from a terminal and unmute and set the mixer levels all the way up. """ This solution worked for me on linux-image-5.6.0-1042-oem AFTER manually opening alsa-mixer and changing soundcard to sof. The sound would otherwise just show 'dummy'. My sounds still do not work on 5.8 or 5.10, full name listed above. I did not get to test this temporary fix with 5.4. my full alsa-info: http://alsa-project.org/db/?f=6a638be0cfbe8ed08a010eb26a7702e324dce5ff based on some google research, this seems to be a common problem: https://www.reddit.com/r/Dell/comments/hj8oxw/xps_17_9700_no_audio_on_linux_also_hardware_is/ https://www.reddit.com/r/Dell/comments/hge2yo/no_audio_on_linux_ubuntu_2004_xps_17_9700_realtek/ https://www.reddit.com/r/Dell/comments/j2kdjw/xps_17_9700_on_linux_audio_issue/ etc...
