Windows 10: High DPC latency causing full audio dropouts on my audio interface

I have been troubleshooting since December, I've uninstalled and reinstalled so many drivers, I've reinstalled Windows. I've updated my Bios, I've checked all my power settings, I've unplugged old drives. I am fully at a loss on where to take this next, so I beseech thee here on the Microsoft forums. Please help me. I just wanted to play Rocksmith with low latency, that's all I've ever wanted. All I've done was open up a Pandora's Box of issues.

High DPC Latency with System Audio Through Audio Interface.

Hi,

The concern you have encountered may be due to a corrupted file or a misconfigured setting.

Many audio problems on a computer can be caused by DPC latency. DPC stands for Deferred Procedure Call. In its simplest form, it is the part of your Windows system that handles driver efficiency. If there is a driver that is taking longer than normal to
process, it may prevent other drivers from being processed in time. The worst case is that it can cause your audio interface driver from responding in time and can cause clicks, pops, distortion and dropouts.

We suggest to update the driver of your audio card. Generally speaking, updated drivers deliver better functionality and improved performance. For the most part, you certainly want to upgrade your drivers unless you have a very specific reason for not wanting
to do so. To perform the task, simply follow the steps provided by Andre Da Costa on this
link.

Should you need further assistance, feel free to get back to us.

Regards.

 

High DPC latency causing audio stutters

Quite different hardware but this may have your attention.

Sound artifacts and high DPC latency seemingly related to storport driver can be caused by switching between Cx power saving processor states. My pci-express add-on soundcard works correctly only if C states greater than C1 are disabled:





If you want to give it a try, see your mobo manual:
