Audio clicks and pops.

Unfortunately, the latest trace has dropped events which make it unreliable for analysis.

I've not seen that error before when starting a trace. Did uninstalling the Precision software require a system restart? I suspect it adds itself as a consumer of system profile events so maybe uninstalling it doesn't cleanly remove itself from that list. I'd suggest restarting the computer and then seeing if you can start a trace with just the command:
Code: 
wpr -start GeneralProfile

Ah :( , i restarted twice , the first time once i removed EVGA's software, the second time when i got that error.

I will try the one you suggest, is the stop trace command the same as the first trace i ran?
 
It's what I'd consider a minimal command for getting typically useful information. I'm basically trying to see if event tracing is actually available. It's supposed to be running in the background by default to some degree and my understanding is the GeneralProfile just becomes a consumer of event providers which should already be running in Windows.

That one went through ok, how do i stop this one ? :D
 
If you just want to stop it without recording the trace to a file:
Code: 
wpr -stop

should work. If you want to record the trace just add the drive, path, and filename like:
Code: 
wpr -stop d:\filename"

Would it be usefull to let this run a little while? Want to view this one? Should i try run a audio trace again?

can do any .

Again, thank you for helping. :thumbsup2:
 
It shouldn't hurt to let it run and if some glitches happen during the trace it might be helpful to have a look. As far as an audio trace I might ask you to try something else depending on if the glitches also happen while playing media.

First, though, I've seen many systems have a variety of problems when they are overclocked. From the speccy report I see your memory is set for DDR4-3200 which is technically an overclock of your CPU's integrated memory controller. The highest setting officially supported by Intel for i7 8700K is DDR4-2666. Have you already tried the DDR4-2666 setting to see if the problems continue?

Hi yes, i have tried the memory at 2666mhz and unfortunetly it made no differance. i do not think the issues are happening while playing media, only web based/ discord and somtimes TS3 (mainly discord for some reason) and games. although i am normally in discord or TS3 while playing.

When i have researched before, for some its a nvidia/realtek/win10 issue, like a conflict, for some its certain things such as network, and GPU on the same thing conflicting, controller maybe? i cant remember and i have tried to research it so much its all abit muddled together.
 
Using the same IRQ, perhaps? If so, that's not supposed to be a problem nowadays but that doesn't mean it can't be. The strange thing is I'm not seeing anything which suggests the audio renderer is being prevented from doing what it needs to do to play audio in a timely manner. If it's not being starved of CPU time then another way it could produce pops and glitches is if it's being starved of data to render. That's not something I've seen be the problem for systems I've looked at so I'll have to look into how to do it properly.

I see you have the latest BIOS but I can't tell the version number of the drivers. Have you installed the latest driver for your Realtek audio and Intel LAN devices from the motherboard product support page?

Yes IRQ that was it i think, i currently have all latest drivers installed from my motherboard support page. Think i am going to have to Start trying other hardware as well. this problem has persisted through 2 gigabyte z370 gaming 7's , first one was terrible , second one was slightly better but not great, removing there Audio driver and using windows generic one would fix the issue, Then the problem still persists on this asus maximus 10 hero but not anywhere near as bad.

I think, i may have to start swapping things out. i can easily try a gtx 970 from my partners pc, just use DDU to remove driver and pre download a driver for the 970. i could also use 1 stick of memory from her pc, i know one stick on its own is not ideal, but it was during the memory price hike and she needed ram to use my crosshair 6 and 1700x. either way, its different ram to try incase this ram is faulty in some way, even though mem test running all night comes back clear.

So , worse comes to the worse... i could try my old amd stuff in this pc also with the 1080ti to try and rule that out. Although i really hope it does not come down to that.
 
Urghh, Yep watching something on youtube this morning, an the Random Noise glitch reappears . Went back on the video several times to see if it was in the video, or bad editing but nope. Will try run a audio trace now while i watch some things.
 
Ok Well i tried today with a gtx 970 installed made no differance, i changed the ram from 3200mhz SK hynix to 2666mhz Samsung B-Die, made no differance. I tried my 3200mhz kit at 2400mhz made no differance, i turned multicore enhancement off so returned cpu to stock clocks. all still the same result.

( edit also changed from dvi D cable to HDMI ) Also no change
 
Thank you for doing all of that testing. I'd like to try something else if possible but it generates very large trace files in a short period of time. Do you have a method that will produce the problem reliably during media playback?

Well, the problem will present itself all of the time with any discord notification sound be it a direct message tone, a server tone, the push to talk tone, voip will start to crackle. I cant say i notice it with media on my pc (music) although i could try test this , i mainly use web based media, however it is sporadic, one boot up/restart it will be there straight away, other times it could take all day to materialise ( apart from discord this will do it without fail and be pretty bad ). Somtimes its bad, other times you hardly notice it. it will do it on games. but i almost always have network based programs open at the same time.

Im willing to try what ever needs to be done to get to the bottom of it.
 
There's a tool from Microsoft called Media eXperience Analyzer which is mainly used to try and track down audio and video playback issues. I've only seen videos of it being used to analyze traces of a computer experiencing noticeable glitches while playing a video in full screen although I'm sure it can do much more. To get the trace you'd need to use the GUI version of wpr and add a custom profile which looks like this when setup to be used on my computer.

To get to that point you need to have first installed the correct GUI version of Windows Performance Recorder. If you type "wpr" in the Windows menu do you get a tile for "Windows Performance Recorder"? If so, go ahead and launch it and let us know what version it is from the About button.

I do get a tile for "Windows Performance Recorder"

This is the info in the about button Untitled.png
 
I believe the 1803 version should work.


  1. You'll need to use the Add Profiles... button to add this profile to the list.
  2. Make sure no other checkbox has a check in its box other than the one shown in my previous screenshot.
  3. That profile only has the option to save a file to disk and I've not found a way to change it. You'll need to have enough room on your C: drive to capture a trace.
  4. The traces will end up in your "Documents\WPR Files" folder.

Please try getting a trace using the Discord glitch producing method you described. You'd hit the Start button, trigger the glitch, and then hit Stop. The files can get very large in a short period of time. I'm not sure it will catch those glitches but it's worth a try. Please make the resulting trace available.

Rather than Stop the button will change to Save which is what you'd click to end the trace and then save it to a file. You can change the save location but I'm pretty sure the temporary file being recorded during the trace is on the C: drive.
