Somewhere along the line, someone's associated some hardware ID codes
with some product names. It's possible that more than one different
product used the same electronic parts, so you may get naming you don't
expect. Some hardware may name itself (it may supply data when
probed).
Why does Built-in Audio Pro appear twice?
What's the difference between "Built-in Audio Pro 1" and "Built-in
Audio Pro 2"?
I don't know why there's two, but it could be front panel socket versus
back panel socket (or different connectors on the motherboard, if you
can only see rear-panel sockets). If they're another USB audio device,
it could be that they support two different methods of audio use.
What are the "Profiles"?
Different ways of using some hardware. Some audio cards have analogue
and digital (e.g. SPDIF) outputs (yours appears to). They may only be
able to use one of them at a time. There may be no way for the OS to
tell which one you've connected, they may use the same jack for
different purposes, so you get to choose.
What is the function of the circles with dots, which look like radio
buttons, but can't be because two of them are selected.
The are radio buttons, the top section (above the line) is selecting
one of three speaker outputs, and the bottom section is selecting one
of two audio inputs. Ignore that it's using a mike symbol, it doesn't
have to be a *microphone* input. Likewise with using a speaker symbol
to represent output.
