Public bug reported: Since updating to Ubuntu 20.04, I have lots of problems with sound input and output coming from the wrong device or even a device that is not turned on. For example, right now in gnome-control-center sound settings it recognizes three sound output devices - internal speakers, HDMI output and a wireless headset. The wireless headset is off and the HDMI has no speakers, but I am using a HDMI->VGA adapter that gives it the impression that there may be speakers. In gnome-control-center, I have set the internal audio to be both the input and output devices for sound. When I click on the button to test audio output, no sound is produced, but if I have pavucontrol open at the same time, I can see that it is trying to send the sound output to the wireless speakers despite the settings in gnome-control-center.
Similarly, if I try to do a video conference, such as skype, sound input and output are almost always wrong. Right now, if I try skype, it will only use the headset speaker and microphone, though it will make the phone ringing sound using the internal speaker. Again, this happens regardless of what I configure the sound settings to be in the skype settings panel. With many other video conferencing applications I have similar problems. With some, I manage to go into pavucontrol and manually set the appropriate devices for input and output, but for others I am often forced to use the headset regardless of whether I want to or not. I have a number of colleagues that report similar issues when trying to use video conferencing software with Ubuntu.
