Sorry to push this old thread... But I have exact the same problem as the users reported already.
The use of latest official AIDA64 6.32.5600 with Gigabyte's RGB Fusion Software (no matter which Version) to control the LEDs of my Gigabyte AORUS GTX 1080 Ti Extreme is not working. Deactivation the GPU Senors (in AIDAs Stability settings) followed by reboot helps but I need them both running together...
According to the posts here this looks like to be solved but - as I wrote - this came back with latest version. Or this problem is related my specific card? - For me it looks like you were bugfixing this for each specifig user setup?!
Enclosed my nVIDIA SMBus Dump with the hope that you can help me as well...
Please let my know if you need any futher information/data.
