That's ok for any Laptop that isn't advertised as "Ubuntu certified".
But I literally had to uninstall Ubuntu and install Arch to get audio and microphone back to work after the 19.04 update broke it, and some dev mentioning on the bug report that the fix wouldn't land on 20.04 which it didn't.
Imagine Microsoft or Apple telling their users that they have to live without a soundcard for 6 months during COVID-19 because "tough luck". Well that's pretty much how Canonical and Lenovo treat their customers.
