C# text adventure - sound issues at the menu

Hello

I have to write a text adventure for school in C# in visual studio 2015. I have made a little starting menu with some options. While the menu is displayed some background music is playing. When you choose an option from the menu a little sound is played but it stops the background music from playing. 

I basically want to play multiple sounds at the same time.

Any help would be appreciated.
