  • Uninstall all Realtek audio drivers from Device Manager
  • Reboot (Windows auto-installs basic HD Audio)
  • Go to Sound Settings > Output and switch to “Speakers (High Definition Audio)”
  • Disable “Audio Enhancements” in properties

Optional: Use older driver version from Razer support page

I have faced the same problem, then same fix worked while testing a sound mod from HappyMod App too
