Kernel-Mode Driver Architecture Design Guide – Windows drivers | Microsoft Docs – Question Info

 

Hello, I recently started getting into audio recording and have been running into a lot of latency issues, audio interruptions, and cracks and pops while recording and using my fire wire connected interface. My computer has plenty of RAM, cpu, power and everything else. I have updated all my drivers to the best of my knowledge and now I cant even continue with using this operating system unless I find a fix here pretty quick. It was reported to me that the wdf Are there any known fixes or updates to address this??

The wdf In the meantime, check out this article for tips on how to improve PC performance. Was this reply helpful? Yes No. Sorry this didn\’t help. Thanks for your feedback. I am able to monitor the output audio and the interface is not detecting the audio interruptions which tells me the interruptions happen between my interface and my computer.

Also I have Windows 10 Pro if that changes anything. I only ran this test for 15 seconds and here are the results:. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution. I have removed the interface from the equation and Ableton live 9 for the past week.

I am now only trying basics tasks like play audio from iTunes and have the browser open. However I am still experiencing latency from the same driver as well as some other Microsoft drivers. I have the exact same problem. I manage to reduce the amount of lag and execution time by disabling my network adapters and audio device in device manager Realtek as Im using the audio device in my controller. I somewhat solve the problem, but it\’s still there after some time playing.

I would like to find another way to solve this. For us to effectively assist you regarding this latency issue you\’re having with your Windows 10 computer, can you tell us if you have tried all the resolutions provided in this thread? If you haven\’t, kindly do so and update us with the result. Also, can you tell us all the troubleshooting steps if there\’s any that you have tried to resolve your concern?

This is for us to avoid repeating them to you. This DPC latency issue is a problem that\’s been persisting in Windows 10 since , as far as google can tell, and steadily, with each and every new system update, more and more people are encountering this problem.

It\’s very frustrating that it seems like these updates are untested, and we wish you would relay this to the development teams at Microsoft. I have literally just re-installed Windows 10, and kept the Ethernet cord disconnected and had no wireless card plugged in before, during, and after the installation to ensure no updates are downloaded or installed.

LatencyMon has been analyzing your system for h:mm:ss on all processors. Note: reported execution times may be calculated based on a fixed reported CPU speed. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

I only have a microphone, a webcam, a keyboard, and mouse plugged in, and disconnecting the mic and webcam does not effect the latency, whatsoever.

Multiple restarts and using my motherboard\’s CMOS clear switch does not help. It should be below for a freshly installed system, and I will now try to replace all Windows drivers with as many provided by my motherboard manfacturer Gigabyte.

One moment, please – INTRODUCTION

 

In some cases, framework objects are incorrectly parented and not deleted after use. With this feature, you can specify a maximum number of objects and what should happen when this threshold is exceeded.

This is the maximum number of objects of the types described in the ObjectsForLeakDetection key. To control whether exceeding this threshold should cause a debug break or a bugcheck, set the DbgBreakOnError key. The SleepStudy software tool reports the number of power references that a KMDF driver has that are preventing the system from going to sleep.

For more info, see Modern standby SleepStudy. You can debug your driver more effectively when you can follow the interactions between the driver and WDF. You can use this feature to step through the WDF source code while debugging, and to learn about framework internals without downloading the source code to a local machine.

Want to benefit from the universal capabilities of UMDF 2? When a driver provides a custom trace, the driver IFR log contains the trace messages. If a driver crashes, the logs are frequently included in the crash dump file.

IFR logs are included in minidump files except when the responsible driver is undetermined or if the crash was a host timeout. If you have a debugger connected, you can access both the driver and framework IFR logs by issuing! If you do not have a debugger connected, you can still access both logs. When debugging a UMDF driver, you can merge framework logs with driver logs by issuing:!

New debugger command:! You can run! You can use! For more information, see! The Kernel Mode Driver Frameworks service is a kernel mode driver. If Kernel Mode Driver Frameworks service fails to start, the error is logged. Windows 10 startup proceeds, but a message box is displayed informing you that the Wdf service has failed to start.
