Und nochmal 2 Sounds Gleichzeitig abspielen...

Delphi-Quellcode:

uses 
  MMSystem; 

procedure SendMCICommand(Cmd: string); 
var 
  RetVal: Integer; 
  ErrMsg: array[0..254] of char; 
begin 
  RetVal := mciSendString(PChar(Cmd), nil, 0, 0); 
  if RetVal <> 0 then 
  begin 
    {get message for returned value} 
    mciGetErrorString(RetVal, ErrMsg, 255); 
    MessageDlg(StrPas(ErrMsg), mtError, [mbOK], 0); 
  end; 
end; 

procedure TForm1.Button1Click(Sender: TObject); 
begin 
  SendMCICommand('open waveaudio shareable'); 
  SendMCICommand('play "C:\xyz\BackgroundMusic.wav"'); 
  SendMCICommand('play "C:\xyz\AnotherMusic.wav"'); 
  SendMCICommand('close waveaudio'); 
end;

Edit:
Die Variante hat leider den nachteil das man damit keine mp3s abspielen kann
