Comment 621 for bug 1958019

Seems like this is the best way to do it (but if someone knows of a better way for Ubuntu, let us know):

Seems this gets you a tool that allows you to manage and install mainline kernels. You'll need a 5.17 (which is the latest stable mainline release) to get your sound working.

Keep us posted.
