That's great! It wouldn't be too hard to get a workaround for the music. Did you manage to get at least one draw of a 3D scene ? There is demos in the Main menu background. If you see something, that means you compiled the shaders properly! That would have been the main obstacle.
For the codec, I use the Content Pipeline of Monogame framework to convert them in a platform specific format. I target Windows, not even sure what format the sound files are converted to. I will do another build for you with no sounds to see.
