FxSound launches but does absolutely nothing — extensive Windows troubleshooting exhausted

I’m completely stuck with FxSound and have reached the point where I’ve exhausted basically every troubleshooting step I can think of.

The original problem was that FxSound would appear to launch, but no interface/window would open, and FxSound’s processing wasn’t affecting my audio. Normal audio through my headphones works perfectly.

Here’s what I’ve established:

  • FxSound is installed normally.
  • The executable is located at:
    C:\Program Files\FxSound LLC\FxSound\FxSound.exe
  • Running the executable directly from Command Prompt previously caused an FxSound.exe process to remain running, but no GUI appeared.
  • The Windows Playback Devices list contains FxSound Speakers, so the virtual playback endpoint exists.
  • Normal devices such as Realtek, NVIDIA High Definition Audio, and my USB audio device work normally.
  • Device Manager does not show an obvious FxSound device/error.
  • There are no obvious corrupted-device errors.
  • There is no FxSound service visible in services.msc.
  • %LOCALAPPDATA% does not contain an FxSound folder.
  • Event Viewer does not show an obvious FxSound crash/error.
  • Registry searches produced no useful FxSound information.
  • Windows system-file/integrity checks did not reveal anything obviously corrupted.
  • Running the executable from CMD returned ERRORLEVEL=0.
  • More recently, FxSound has progressed from launching invisibly to not appearing to start at all.

I have also already reinstalled the appropriate motherboard/Realtek audio driver, and I really don’t want to keep removing/reinstalling functioning Windows audio drivers because normal audio itself is working.

At this point I’d really appreciate help identifying what component of FxSound is failing to initialize, particularly the GUI/backend/virtual-audio processing side.

Is there a specific FxSound diagnostic/logging procedure, command-line argument, debug mode, or clean-removal procedure that can reveal why FxSound.exe isn’t initializing?

I’m happy to provide logs, screenshots, Event Viewer information, Process Monitor traces, or anything else needed.

Thanks.

Can you check if FxSound process is present in task manager? If it is present in task manager, select End task to kill the process and then run FxSound.exe again.

What is the FxSound version that you have installed?
