I have the same, just got it two days ago. Unforntunately even with installing the release candidate rc4 and rc5 of kernel5.17, the sound does not work. When going to sound settings it does not list anything as output devices.

I am using ubuntu 21.0 actually.

Any idea?

I also had plenty of issues setting the bluetooth connections to my keyboard, gnome-shell is consuming CPU like crazy etc - so seems like some kind of outside force is trying to keep this PC and ubuntu as far as possible :D
