If you're not noticing any difference in the change of sound quality (or you're not seeing the visualizer/spectrum bands move) after installing FxSound or DFX, try the following steps for Windows 10:
1) Click the sound icon in the bottom right of the taskbar
2) Click the playback device you're currently using to select from an option of playback devices
3) Scroll through and find and select DFX Speakers (DFX Audio Enhancer)
4) Test audio playback with FxSound or DFX running!
