There is a question here very similar to my issue but it has not been answered.

Some time after I re-installed Windows 8.1 on my Asus X551CA the sound would stutter regardless of whether it was an online stream of audio or a mp3 on my hard drive. It would go away for a while if I rebooted but it will come back after a couple of hours.

It will stutter mostly when there is a quick change in the pitch of the audio stream and other random times. There are times when it won't stutter at all and other times when it stutters for a while.

I downloaded a DPC Latency Checker and I noticed that when I disabled the Realtek PCIe FE Family Controller from Device Manager the latency would disappear and audio worked perfectly...however that driver is responsible for my internet connection so I can't just leave it disabled.

I tried rolling back the driver to the one from 2013 but that didn't help. I downloaded the most recent version also and installed it from the Realtek site but the problem persists.

How can I fix this latency issue and still have internet connection capabilities?

  • try different driver versions until you find a working one. this is a driver issue – magicandre1981 May 10 '17 at 15:00
  • Try to delete the Realtek device in Device Manager and reboot, to let Windows install a clean driver version. Are you using the driver from October 2, 2017? You could also consider upgrading to Windows 10. – harrymc Oct 15 '17 at 6:55
  • @harrymc I will try that tonight, thank you. I want to keep Windows 8.1 though. – NULL Oct 16 '17 at 13:15
