Issue with volume control when THX Spatial is enabled.

There is a 1–3 second delay when I change the volume in the Windows mixer, Media Player, or Spotify. Also, when I start playing music or a video, the volume is too high for 1–2 seconds. This only happens when Windows enhancements are enabled; if I turn them off, the issue goes away, but then THX Spatial stops working—and I need that for gaming. The problem also returns if I switch the audio mode to stereo within the Synapse utility itself. I’ve already tried everything possible—even reinstalling Windows and the drivers, removing Microsoft audio drivers, and toggling exclusive mode—but nothing helps. What should I do?
