if you want to import System sounds like Asterisk,Beep,Hand and others you should import the namespace System.Media but if you want to add a project that plays any kind of sound formats you can use a DirectX component called Quartz.dll which is part of Windows MediaPlayer and Windows Operating system.This file you can find in this path: C:\WINDOWS\system32.Open the Visual Studio Command Line and type the following command:[WindowsDir]/tlbimp quartz.dll /out:QuartzTypeLib.dll.The [WindowsDir] is where your instalation of operating system is(in most cases C:\).I hope I helped you cause I had the same problem and should digging a lot to find a way to play sound formats.Best wishes! :)
