Have a look at MCI command strings reference and this helper function :-

bool mjdomcicmd(AnsiString cmd,bool shwres,AnsiString cmp)
{
  char erst[9999]; erst[0]='\0';
  int mcierr=mciSendString(cmd.c_str(),erst,9990,NULL);
  if (mcierr!=0) { mciGetErrorString(mcierr,erst,9990);
ShowMessage(AnsiString(erst)); return false;}
  else if (erst[0] && !cmp.IsEmpty()) return
(AnsiString(erst).LowerCase()==cmp.LowerCase());
  else if (erst[0] && shwres) ShowMessage(AnsiString(erst));
  return true;
}

and use for example is :-

mjdomcicmd("open new type waveaudio alias phsnd wait",false,"");

MCI is easier to handle than waveIn etcetera, especially when it comes to
video mixing. Have a look at the "setaudio" MCI command to see what I mean by
easier.
