This is still a bug in 20.04.3 LTS. It's a fresh install with proprietary drivers enabled from the installer. Could it be routing analog audio to the wrong place? I can get it to work fine with bluetooth headphones, usb headphones on the dock and the laptop. I can't get any audio from the analog jacks on the laptop or the dock or the built in speakers.
