Status changed to 'Confirmed' because the bug affects multiple users.

[Samu (samulx)]

I tried the same and the touchpad is not recognized for me as well. Would be really nice to get a fix here.

Furthermore, audio is not working either.

Is it working for you after a fresh install?

[Matteo Croci (croci)]

Yes, audio is also not working for me unfortunately.

Camera is also not working. It would be good to know if these issues were fixed in a later kernel.
