Thanks,

But that didn't work for me. The speaker is still red and in device manager the warning stays.

I just finished a clean install of Windows 10 (64-bit) on my PC, and everything worked smooth untill i installed the audio drivers for my motherboard. After the drivers update, my computer were only able to detect my monitors as sound output devices, and not my headset. I checked my audio drivers, and saw that Realtek Audio had an error code 52. To fix this i fix tried to manually reinstall the drivers again, which didn't work. Afterwards i tried to delete my UpperFilters and LowerFilters registry values, but i was not able to find them. As a final desperate fix i tried to safe boot with disabling driver signature enforcement enabled. This solved my problem, and my sound worked smoothly. The problem is that now i have to safe boot every time i want my audio to work, which is really just a pain in the ass. Does anyone know a fix to this?
