hi i use Tixtrackbar to control on volume level i do somthing like this

Code: Select all

procedure Tvolfrm.VolumeChange(Sender: TObject);
var
  i: Integer;
begin
  i := TrackBarToValue(Volume.Position,Volume.Max,Volume.Min);
  if Not volumeClose then
  try
//any thing
  except
  end;
end;

but the level never changes any hint ?

Hello,

I am not sure if what you wanted is to change the volume, but, if so, are you sure the AudioMixer can do it in the way you expect? Personally I use the TAudioVolume Delphi component by Silhwan Hyun and the work like expected (change the system master volume level) at least in Windows 10, 8.1, 8 and 7. Maybe you want to take a look at this component.
