Can confirm here with Kubuntu 20.04 with kernel 5.4.0-40-generic and kernel 5.7.14... Sound works through head phones (using either bluetooth or a analog 3.5 mm cable). I did notice that playback via bluetooth stopped once... After putting the laptop to sleep then waking it back up, audio via bluetooth resumed.
I do not know if I am able to get audio via HDMI, I'm unsure how to use that setting (or is an external HDMI monitor needed for that?).
