In addition, we can find 
"Main audio device could not be initialized. Please check the value for AudioDeviceModuleName and AudioMixerModuleName in [Platform]Engine.ini."
log message in the engine.
It is appropriate to remove the AudioDeviceModuleName since it is no longer referenced anywhere in the engine.

Steps to Reproduce
  1. Open Confing/Windows/WindowsEngine.ini
  2. Put following configs
    ; WindowsEngine.ini
  3. launch the editor
  4. see logs


Even though the internal audio system is intentionally disabled, "Audio Device Manager Initialization Failed!" warning is output.
