Detect whether there is a sound card installed

If you need to detect whether there is a sound card installed, your application may call the function 'waveOutGetNumDevs' from the multimedia DLL (winmm.dll, part of a standard installation). // declare by a nicer functionname.. function SoundCardInstalled : longint; stdcall; external 'winmm.dll' name 'waveOutGetNumDevs'; // use like this.. if SoundCardInstalled > 0 then Showmessage('A sound card was found.');
