Interesting. Not sure what the deal is. Someone is suggesting that at least for PulseAudio, it could just be the older version of PulseAudio that shipped with Ubuntu. However, you should be able to get it working on Pipewire just as well. Pipewire stuff is still pretty immature, so your distro may have an older and less stable Wireplumber at the moment. In that case, it might be worth just trying to set the Pipewire Media Session option for this instead. Wireplumber is really powerful, though, so it's a nice tool to have available.

+1 For Pipewire + Wireplumber! With it, automatic codec switching has worked quite well for me!
