How to detect a sound device

Problem/Question/Abstract:

Is there a way to detect a sound device (personally, I want to detect a sound card) to know if such a device is present on the computer my application is running?

Answer:

Solve 1:

{ ... }
if WaveOutGetNumDevs > 0 then
  ShowMessage('Wave-Device present')
else
  ShowMessage('No Wave-Device present');
{ ... }


Solve 2:

function IsSoundCardInstalled: Boolean;
type
  SCFunc = function: UInt; stdcall;
var
  LibInst: LongInt;
  EntryPoint: SCFunc;
begin
  Result := False;
  LibInst := LoadLibrary(PChar('winmm.dll'));
  try
    if LibInst <> 0 then
    begin
      EntryPoint := GetProcAddress(LibInst, 'waveOutGetNumDevs');
      if (EntryPoint <> 0) then
        Result := True;
    end;
  finally
    if (LibInst <> 0) then
      FreeLibrary(LibInst);
  end;
end;
