I am playing with SndPlaySound. I need to wait until the file has played, or to receive some message when it done.

Please advise how to do it.

Thanks.

Do you have the audio in a .wav file or in memory?

You should do something like this:

if PlaySound(PChar(FileName),0,SND_SYNC) then
  Shoemessage('Sound played');

I tried the sndPlaySound(PChar(sFile), SND_SYNC) (I wrote it in my question) - but it doesn's stop - it continue to next line.

Try example given by marqusG. sndPlaySound function is old. MS suggest PlaySound:
PlaySound(PChar(sFile),0,SND_SYNC or SND_FILENAME);

Agreed with sinisav, below code works sync here:

unit Unit3;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm3 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form3: TForm3;

implementation

uses
  MMSystem;

{$R *.dfm}

procedure TForm3.Button1Click(Sender: TObject);
begin
 PlaySound(PChar('somewave.wav'),0,SND_SYNC or SND_FILENAME);
 Form3.caption := FormatDateTime('zzz', Now());
end;

end.
