Rich, a dumb question just to confirm the obvious:

Do you have a MP3 codec installed? RB doesn't have that automatically unless you're on 2018 with the latest build.

This is an example btw of you not providing that info in your first post. See my sig info at the bottom of this reply, you should provide us with all that too.
