Bug Description

Some two hours ago, I listened to audio through the extenal monitor, also used as display. Then I upgraded to 20_04 from 18_04. Now the display still works, but pulseaudio doesn't see nor offer the HDMI sink any longer on my lenovo T410s.

What a bad mishap ... . And what to do now?
