Latency/DPC issue - Audio clicks and pops.
- Thread starter doc46
- Start date
Try to completely remove avira.
Im having the exact same issues with the dxgkernel.sys and also storport.sys and i bet you a million dollars that there are lot of people with the exact same problem who have never installed any third party antivirus system , have no USB sound devices connected just like me and are using ASUS onboard REALTEK sound. Also the OS is running off a M2-PCI EXPRESS Samsung and not loading any stuff from a slow sata drive.
My DPC spikes to hell when playing anything with audio and i have pops and crackles every couple of seconds on my sennheiser headphones connected to the front panel. I also tried a whole bunch of thing including turning off Speedstep , setting the nvidia driver to always prefer maximum performance, changing power plans to ultimate (im on enterprise windows 10) and what have you not. The rig is quite a beast with a 6 core coffee lake, and a 1080, XMP Profile Corsair ram..etc
It drives me nuts.
And to the dude dont worry about your antivirus ..use the microsoft built in antivirus im on the net for 30 years now and the past 10 i have been using nothing else..its as good as anything else and causes next to none issues.

Hi thanks,
I will try Microsoft defender to replace Avira.
I disabled Reaktek audio device from BIOS, disable Nvidia HD audio drivers (only install graphic driver) so I only use Scalett 2i4 audio drivers. In my case this is better than at the beginning, because it was like you, now I only have a "Bippppppp" sound bug latency sometimes, and somes crackling, but yes it's really annoying. I'am wasting my times in trying to resolve this issue while I would like to make some music...
Did u try to update BIOS, and drivers from Asus website ?

like i said the DXGKERNEL.SYS problems are connected to the Nvidia Drivers but like always in such scenarios that doesnt mean they must be the ones causing the issue.
1080 STRIX 8 GB
CPU is watercooled 6 core I7 8700 K
mainboard ASUS ROG STRIX-F Z370
( i can clock this baby to 5ghz without even a drop of sweat)

Yes, I really think about buying an AMD GPU

edit : forget what i said ..the problem with DPC latency is still there but at least i cant notice any audio crackle atm.
That snappy driver installer still is awesome !
It just took longer for the DPC problem to show up again...but the spikes are MASSIVE up to 2600 ms which is insane!

@doc46 - The screenshots you've posted only suggest a problem with storport.sys latency. The top two bars of LatencyMon should be ignored unless you're running nothing else on your system according to Resplendent Software's own documentation. The ETL traces suggest the storport.sys driver is the source of the problem as well. Something is making DPC processing of storport.sys intermittently take a very long time. Since antivirus is involved with reading/writing to storage devices it makes sense to remove it as a variable which is what xilolee is trying to do. Randomly trying 3rd party driver installation software was not suggested and likely introduces unnecessary variables into a process of elimination.
Are you still having the audio glitches after uninstalling Avira and using only Windows Defender? If so, what storage devices are you using? Do you have a RAID setup? The screenshots of the event viewer log suggests a problem I've seen on some RAID systems. Namely, Windows gets confused about drive identifiers which I've seen be the source of bugchecks. My suspicion is that Windows is getting intermittently delayed while trying to sort out the drive identifier conflict.

I further investigated and turned Windows Defender Realtime protection off and voila ....running the test for 6 minutes while playing a youtube video 1080p ..no spikes on anything BUT
i turned on Windows Defender in the same scan session again and let it run for another 6 minutes while playing the video... NO SPIKES... So again a shot in the dark.
And being the blind old geezer that i am ..i actually missed that the tool does not report in the usual Miliseconds but in MICROSECONDS..so the actual latency when reading 2600 is 26 ms.

I uninstalled Avira antivirus, I have the same problems a big storport.sys driver spike causing a sound like "Bipppppppppppppp" and a big latency spike.
BIOS setting is AHCI (not RAID)
I have :
- 1 HDD SAMSUNG 750 Go HD753LJ SCSI (E:/)
- 1 HDD Seagate 2 To (A:/)
- 1 SSD CRUCIAL 1To CT1000MX500SSD1 SCSI (C:/)
http://speccy.piriform.com/results/ytBESmZYldZ7XVGvendrX6r
I renamed Seagate 2 To to letter A:, maybe it is this problem :
Should I change HDD letter ?
I think I need to reactivate windows backgrounds apps, I have errors with CLSID and "Windows.SecurityCenter.WscBrokerManager" ?
Have you tested the health of the drives in your system?
I'm not sure if changing the drive letter would cause such a problem. Drive letter A is usually reserved for floppy drives for systems that have them and I honestly don't recall the last time I saw a system with the drive letter A being used. If you've installed programs on that hard drive and changed the drive letter since, it could be that some registry setting is hardcoded for whatever the drive letter was previously but I would be expecting crashes rather than long DPC processing problems.

There should be a new firmware for your Crucial SSD.
