Lost my sound on Fedora 34

Had a few problems with my Fedora 34 which appeared as I changed desktop as processor had blown,

Now I have no sound. Sound shows Digital Output Last time It had two pictures I had to change to another digital for my DGM monitor…

Any ideas what is missing now?

Sometimes sound is difficult on my machine, as well. In the settings GUI I have to find sound preferences and make sure that the correct device is being used in order for things to work properly. Have you done that?
