Referencing this Question/Answer (and many others like it): XNA 4.0 cannot create an AudioEngine
I cannot seem to get this to work. Any help would be super appreciated as the solution linked is NOT working for me and I've googled a lot about this and everything seems to reference the same solution. I know how to add references and have done them successfully in the past, and I additionally have the correct using statements at the top so I'm not really sure what is going wrong, but AudioEngine will not show up for me. If anyone can help I would really appreciate it, thanks!
