Microsoft Teams - No speakers

Fedora 33 with nightly pipewire on a ThinkPad T14s

I need to use MS Teams, but with pipewire it either tries to use my Dock USB speaker which is not connected to anything, or if I disable that in pavucontrol (configuration, ThinkPad Dock USB Audio - Off), it complains that there is "No Speakers".

In teams, going to "Device settings", shows "Speaker: None" in this casepwdump.txt.

For Microphone it does show "sof-hda-dsp Digital Microphone" and it works.

The MS Teams application is build around chromium.
