How can I detect if a sound device is present on the computer were my application is running?
Use this code sample to detect if there is a sound device on the machine your application is running on. Make sure you add the unit MMSystem to your uses clause.
procedure TForm1.Button1Click(Sender: TObject); begin if waveOutGetNumDevs > 0 then ShowMessage( 'Wave-Device present' ) else ShowMessage( 'No Wave-Device present' ); end;
