I have the same problem. I ran Pop!_OS 20.04 from USB and the bluetooth worked fine. And after doing a clean install, bluetooth also worked. But when I did the initial updates, I had the same problem: device appeared in settings and connected, but no sound. Something in the initial updates messed things up.
