I was using SoundEffectInstance. It was provide me playing more than 1 sound at same moment. How can I do it in Windows 8 Metro Style, WinRT applications?
Thank you for your help.
XAudio2 is your friend, you can also look at multiple answers that use this via SharpDX if you want to stay in C#. For an example see How can I play multiple sounds at the same time using SharpDX in WinRT?
