I'm having a problem with the music during installation.
If the operating system volume is at 30%, when I run the installer, it automatically goes to 100%.
Could you suggest a code that does not affect the volume of operating system?

This is the code I'm using:

#include "botva2.iss"
#include "BASS_Module.iss"

procedure InitializeWizard();
begin
  ExtractTemporaryFile('BASS.dll');
  ExtractTemporaryFile('CallbackCtrl.dll');
  ExtractTemporaryFile('botva2.dll');
  ExtractTemporaryFile('MusicButton.png');
  ExtractTemporaryFile('Music.mp3');

  BASS_Init(ExpandConstant('{tmp}\Music.mp3'))
  BASS_CreateOnOffButton(ExpandConstant('{tmp}\MusicButton.png'), 20, 320, 36, 36, 4)
end;

procedure DeinitializeSetup();
begin
  BASS_DeInit;
  gdipShutdown
end;

Thanks in advance.
