Why doesn't PlaySound() play sound?

Question

C++ / C#

PlaySound()plays standard system sound instead of .wav file. Here is a listing of the function where it is used:

void Scene1()
{
            if(SelectNumber == 1) //Rock
      cout << "You played Rock and Computer played Rock. It's Draw ;|" << endl;
               else if(SelectNumber == 2) //Paper
         {
        cout << "You played Paper and Computer played Rock. Paper covers a Rock. You WIN ;)" << endl;
      LPWSTR win = L"D:\c++_progs\testing\Release\winsound.wav";
      PlaySound(win,NULL,SND_ASYNC);
         }
               else if(SelectNumber == 3) //Scissors
         {
        cout << "You played Scissors and Computer played Rock. Rock smashes Scissors. You Lose ;(" << endl;
      LPWSTR lose = L"D:\c++_progs\testing\Release\losesound.wav";
      PlaySound(lose,NULL,SND_ASYNC);
         }

Herself PlaySound():

LPWSTR win = L"D:\c++_progs\testing\Release\winsound.wav";
PlaySound(win,NULL,SND_ASYNC);

I connected Winmm.lib, tried it earlier on other projects - it worked. Now I'm doing something wrong.
