Bug Description

I had an alert to do an update today from the software-updater so I went ahead as usual and did the update.

As a result I now find that I get now sound out of my speakers. This is true on this machine and on another machine that has the same Ubuntu version (but slightly different hardware & different speakers).

In the pavucontrol when music or video is playing I have checked that nothing is muted. And I used alsamixer to turn off any muting there. And in fact there is only one sound output device (my speakers) and the sound is being shown since the indicator that shows decibels shows continual movement.

So actually, I don't think this is a bug in pavucontrol but in the sound system generally, but the bug report tool only lets you specify an actual package.

There have been pulse audio updates since I reported this, and after today's updates (and deleting ~/.config/pulse), the two computers that had the problems now correctly output sound from the speakers.
