No Sound "Dummy Output" AMD Family 17h HD Audio

[zabadabadoo]

I don't now if this will help you:

No sound, please help!

"Dummy Output" OK, we see occasional cases of that. Websearch using AMD/ATI Device 1637 dummy output ubuntu 20.04" for your sound device gives: Only suggestion I see is maybe try a later linux kernel. But using a later version kernel not tested by Zorin devs may or may work, but could give you other issues. EDIT: Did you try this: pulseaudio -k && sudo alsa force-reload Also: I see you have bought Pro. That gives you entitlement to support from Zorin devs. You could try an email to them…
