High DPC Latency Issues

[Boomwebsearch]

This issue all started while I was watching content on my computer and I heard popping within the audio being outputted by my integrated speakers in my desktop. After searching around the internet I found out that this issue was being caused due to high DPC latency which I came to find out using a software which measures the DPC latency of your machine and states if it is going to be a potential problem In playing back audio or not. It was detecting high DCP latency which I am not really sure about what I can do in order to solve the issue. The two playback devices which I have are "Speakers (High Definition Audio Device)" and "Speakers (XSplit Stream Audio Renderer)". How would I be able to solve the issue which is being caused by the DCP latency?

whats your OS and what DPC software did you use to check?

My operating system is Windows 10 and I used an application called dpclat.exe in order to check the DPC latency in my computer and that showed that the DPC latency was causing my problem.

What drivers there are with highest execution times?

that program doesn't work correctly on Windows 10, use this instead: http://www.resplendence.com/download/LatencyMon.exe
open it and press start on the top left corner, then go to Drivers Tab, to check which is causing this latency issue.

I installed LatencyMon on my computer and found out that the highest execution times are created due to the drivers of "ndis.sys" , "ataport.SYS" , and "tcpip.SYS" . 

[EsaT]

Did you experience any of sound issues during that?

Monitoring should cover times of those to give reliable hints.

And were execution times in class of millisecond or more?

 

Anyway those would be mostly motherboard related, so do you have latest drivers for chipset and LAN controller?

I have attached an image from LatencyMon which shows the drivers causing the most execution times (listed from the most to the least amount of time). During the course of the test I did experience popping and lagging audio being outputted which was experienced in watching content with the test running in the background. My LAN controller has the latest drivers although I am not really sure towards the chipset due to not knowing where you would be able to check for driver updates on the chipset.

[Boomwebsearch]

I have let LatencyMon run in the background of my computer for around 3 hours and the result of this test is shown in the attached image. I am not sure about how I can solve this issue with DCP latency which would in the end remove the popping and crackling sound added into audio being played back. Please let me know how I would be able to resolve this problem. -thank you

That NT Kernel issue might be triggered by something else.

Only others are basically network related so that's likely primary cause:

There's that McAfee clearly having issues, so trying another AV could be one thing.

And then those chipset/LAN chip drivers.

 

What motherboard you have?

Besides motherboard makers site AMD and Intel have drivers for their chipsets.

Also NIC drivers can be found separately.

This computer is a pre-built machine created by HP so I did not take not of the motherboard contained within the computer when I bought it although the computer is an HP DC8000 with a Intel Core 2 Duo E7500 as its processor.

Chipset is Q45 express.

https://support.hp.com/us-en/product/hp-compaq-8000-elite-small-form-factor-pc/4065894/document/c01926347

Intel's page might have newer drivers if you search for it.

Though wouldn't have high hopes for proper Windows 10 drivers for such old PC.

 

NIC aspect seems to be more messy.

Device manager should say something in Network Adapters.

I have been trying to ignore the lag in the sound although I think that it is getting to the point where it is an actual problem when playing back audio. This has not been happening in the past and I noticed this just one day when playing back some audio which was poping and lagging. I am not really sure what I am going to do towards this problem and solving it. Is there possibility that something hardware based (damage) is causing the problem. This is my primary system so I would like to have the issue resolved quickly if possible as it is getting more and more annoying when playing audio. I have included a file which has my network drivers. I am not sure why this started happening either. Please help me find and solve the problem. -thank you

@Boomwebsearch
it's possible that the network drivers are not compatible with windows 10, because your PC is really old 

i am not sure what the issue is, send it to someone who can help?

you could try going back to windows 7 or something

I bought this PC in the refurbished state and the Microsoft authorized refurbished loaded it with windows 10 and that was what was l had on the machine the first moment I got it in the mail. I have never used this machine with Windows 7 and would not like to go back to Windows 7 because I do not have a copy of that OS and because I prefer Windows 10 a lot more than Windows 7 which I have used with one of my laptops in the past.

i really dont know anyone here  i meant send it to a PC technician, as its easier to fix the problem hands on, it's really hard to tell what the problem is just by looking at the info you gave.

I am trying to avoid a trip to the repair shop by asking for a solution to this problem on the Linus Tech Tips forum. Although in the very worst case I might have to take my PC to the repair shop in order to get the problem solved. -Thank you so much for your time in trying to help get the issue fixed.

 

 

 

If anyone happens to know the solution to this issue or have any ideas on potentially how to get the problem fixed please post them in this thread.

That's quite a lots of stuff in Network Adapters.

Intel NICs are usually well working, so I would be looking more to that Bluetooth and WLAN adapter.

What's the particular model of those?

 

Also what kind internet connection you have?

If it's through wired LAN or WLAN those WAN Miniport things are likely just unnecessary crud.

Microsoft loves filling PCs with ever increasing amount of useless for average user background stuff.

And that ancient hardware simply doesn't tolerate any resource hogs.

I have a subscription to cable internet and therefore have a coaxial cable going from the cable outlet to my cable modem, and an ethernet wire running from the cable modem to my wifi router. My PC has a USB wifi adapter and also is connected with an ethernet cable to one of the ports on my router (acting as a switch basically). I am connected with a wire most of the time although I sometimes use the wireless connection. I disabled the driver for my USB Bluetooth adapter and that seems to lower the lag in the audio output although it is not removed fully.

For Bluetooth, I use a driver named as "Generic Bluetooth Radio" which I currently have disabled at the moment and for the wired LAN, I am using an Intel(R) 82567LM-3 gigabit network connection. And am using a driver called "802.11n n USB Wireless LAN Card" which corresponds to the device of some unbranded and very generic looking USB wireless adapter which I ordered on eBay and do not know much about its manufacturer or model specifically.

So modem should act as router with PC having local network IP.

Those WAN Miniport stuffs are used by VPN connections so if not using such you could test disabling those.

Also having both wired and wireless connection might cause conflicts, so test with WLAN disabled/without that USB WLAN adapter.

If you have cable anyway attached to router that's more sure connection, than some who knows what chip using WLAN NIC.

 

With disabling Bluetooth adapter decreasing problem we're certainly on right track.
