After upgrading to ubuntu 20.04 the hdmi sound stopped working. If I select headphones as audio output they work well, but if I change to HDMI output it doesn't work.

Also I noticed that when I select HDMI output the "configuration" option disappear.

If I select headphones as output, the configurations look like this:

when I select HDMI output, the configurations look like this:

And no sound is played.

What can I do to fix this?
