Ubuntu 20.04: No sound

Hi

I've installed Ubuntu 20.04 LTS on my old (but upgraded) Sony Vaio
laptop. Before, it was Kubuntu 18.04.

Now, sound doesn't work in the laptop. In the system settings there is
an item "sound" (Klang), and there isn't any output device listed. The
only entry in the output device list is "Dummy-Ausgabe" (dummy output).

It worked without problems, when I still had Kubuntu 18.04 on that
laptop.

I've googled the web, but couldn't find anything which applies for my
case.

Any hints?

Regards,
Volker
