Asrock P67 Extreme4 UEFI & Drivers thread [Extreme6 & Pro3 owners welcome]

just an observation..
with 0.110 i get crackling sound on realtek....

Yes, another user had this problem with older drivers. He found that the Etron controller was causing extremely high latency and the issue was present with several types of sound cards:

I may have solved the problem. I had problems with all my audio devices (though only the two creative cards needed reboot), but mostly while playing games:
- Realtek onBoard Sound - bad sound / heavy distortions
- Asus Xonar DX (PCIe) - bad sound / heavy distortions
- nVidia Audio (HDMI) - bad sound / heavy distortions
- Creative X-Fi Titanium (PCIe) - bad sound / heavy distortions / sound crash (need reboot)
- Creative Audigy 2 ZS (PCI) / bad sound / heavy distortions / system crash (need reset)

I found out that I have very high DPC latencys (sometimes >100000 µs) and that the problem is the onboard Etron USB 3.0 controller. I left a game running in the background and deinstalled the Etron drivers while monitoring the DPC latency. The latency fell from red (more than 50% off the values were above 10000µs) to normal green just as the unistaller finished.

See this thread, search for Etron:
