Fedora-33 No Sound

[Bob Goodwin]

In a new install of Fedora-33 desktop I have no sound. I have fiddled 
with the problem for several days to no avail so I guess I need to ask 
for help.

PA Volume appears to get an input but i see no output ...

The system had sound with the previous install which was removed when 
anaconda did the present install. Any ideas, suggestions, whatever?      Bob
