If you have a Windows 10 system with Realtek Audio, you're probably aware that the Realtek Sound Manager isn't on your system.  Earlier drivers (R2.81) are fine, but the R2.82 drivers don't work.

Never fear, Realtek released new, updated drivers on January 18, 2018 and you can install them on your Windows 10 32bit or 64bit system. And you can use their advanced RealTek Sound Manager to make critical adjustments to your audio system. Enhance your music, video and games experiences by configuring your speakers to exactly what you want to hear.
