Bug Description
New laptop - Dell XPS 17, bought in 2020. Upon installation of Ubuntu 21.04 sound does not work at all. System settings only show one audio output - "Dummy output". Audio input does not have even that, just an empty drop-down list.
Issue can be fixed if we load a custom sound driver as described here: https:/
That poses a security risk however and according to the author of the article is not necessary since mainline Kernel release 5.11 now has required device headers included.

Looked around for soundwire drivers, found this:
user@MYPC:~$ lsmod | grep soundwire
soundwire_intel 40960 2 snd_sof_
soundwire_
soundwire_cadence 32768 1 soundwire_intel
soundwire_bus 77824 7 regmap_
snd_soc_core 294912 8 soundwire_
snd_pcm 118784 14 snd_hda_
Maybe using the soundwire_intel driver would fix the problem? Need to keep digging. Will post an update if I have any progress.

This also happens in Ubuntu 21.04 installed from scratch and with Kernel 5.11.0-16-generic, so this issue is not fixed by updating the kernel to 5.11.
