XPS 13 9310 Upgrade to Ubuntu 24.04 : no wifi no sound

Dear team,

I upgraded from Ubuntu 22.04 to the latest LTS release after 1 month but it went pretty badly:

* no sound available (card is no recognized only dummy output)
* no wifi
* it runs kernel 5.14.0
The last point is really surprising to me because everywhere it states that 24.04 comes with kernel 6.8.
