Here's the fastest way:

这是最快的方法：

uses MMSystem;

procedure TForm1.Button1Click(Sender: TObject);
begin
  sndPlaySound('C:\Windows\Media\Tada.wav',
    SND_NODEFAULT Or SND_ASYNC Or SND_LOOP);
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
  sndPlaySound(nil, 0); // Stops the sound
end;

With the function sndPlaySound from the WIN32-API (Unit MMSystem):

使用 WIN32-API（单位 MMSystem）中的 sndPlaySound 函数：

sndPlaySound('C:\Windows\Media\Tada.wav', SND_ASYNC);

sndPlaySound('C:\Windows\Media\Tada.wav', SND_ASYNC);

Simple:

简单的：

procedure PlaySoundFile(FileName: string);
begin
 if FileExists(FileName)
 then PlaySound(pchar(FileName), 0, SND_ASYNC or SND_FILENAME);  

 { Flags are:
    SND_SYNC  =0 = Start playing, and wait for the sound to finish
    SND_ASYNC =1 = Start playing, and don't wait to return
    SND_LOOP  =8 = Keep looping the sound until another sound is played  }
end;

People are also quoting sndPlaySound but this is for backward compatibility only. So, don't use it!

人们也引用了 sndPlaySound 但这只是为了向后兼容。所以，不要使用它！
