Audio staggering in Windows 10

Before upgrading to Windows 10, check if there are drivers written for your hardware specifically for Windows 10. You should definitely check that drivers exists for your network card and your audio card.

One reason is that Windows 10 suffer from the same (and important) problem Windows 8 suffer: High DPC (deferred procedure call) latency. If the drivers do not work properly you may have high DPC latency, which may result to audio staggering, lag, clicks, drop outs even if your CPU does not reach 100%. This means that there is a high chance you won’t be able to playback movies flawlessly while using the network card! What a break dealer!!!

You can verify if your system suffers from high DPC latency by using LatencyMon. To learn what DPC latency is read this article.

If there is no Windows 10 driver for your network card, the easiest thing to do is not to upgrade to Windows 10 !!!

Now, what do we do if we have upgraded to Windows 10 and do suffer from undesired DPC latency? There are numerous solutions in the net. Most of which do not work.

Imho, you should complete the following steps by order referenced. If the problem is solved at any point, you don’t have to (and better not to) complete the rest of the steps.

Step 1: Update your system completely.

Step 2: If possible, remove 3rd party antivirus and firewall software.

Step 3: Remove any software you don’t need (you should do that anyway)

Step 4: Update all drivers to latest version.

At this point, if the problem persists then most probably one of your drivers is faulty or not completely compatible with Windows 10. There is also a slight chance that Windows 10 install an invalid version of the driver. You can find which process causes the problem by using LatencyMon but you can bet it is the network/wireless driver.

The only thing you can do is rollback to an older version of the driver or install another one of the same family. So there are two more steps to do:

Step 5: Verify that the driver installed is for the correct hardware model and not just for the correct hardware family. If your card is named 6200 then your driver should be for 6200. Anything else like 6201, 6205, 6300 is not acceptable.

Step 6: Find the proper driver for Windows 7 and install it

If the last step does not work, then you can try other drivers from the same family but you should be careful because this could lead to BSOD screens (so it is not recommended if you are a newbie).

Lastly, if the problem still persists after the last step then there are two more steps but they are both long shots and should definitely not apply them if your problem does not persist:

Step 7: Optimize BIOS:

Important settings to disable (and potentially help provided you do not need them enabled) are:

  • Virtualization
  • High precision timer

Step 8: Update the BIOS

Personally, I don’t think the last step helps. But many people claim it does, so you have nothing to lose.

 

At this point, if the problem persists you are unlucky. You may have to rollback to Windows 7 or install a version of Ubuntu. There are plenty that are fast and user friendly.
