Here you go. Hope this helps:

It seems there are high interrupts in your storage subsystem. Even though there are many factors that could cause this, I would start with installing the latest version of Intel RST driver, as the system is using default Windows storage driver instead of the one provided by the chipset vendor.

Okay, thanks for identifying that. How would I go about installing the new drivers? I've done the setup for Intel RST and I've downloaded the ZIP file with the driver files but I don't know what to do with them. This may seem very obvious but I'm terrible with computers haha.

Download SetupRST.exe from the link I have provided and run the setup. Reboot the computer afterwards. See if the issue persists and if it does, provide a new trace.

Do I need to activate RAID at all in BIOS? I remember seeing that there when I was using BIOS to overclock my RAM.

No, it is not related.

It didn't fix the sound stuttering

Here is the new trace: https://onedrive.live.com/redir?resid=D64E8DF2EC1DCB59!107&authkey=!AG7UkOjJI0kc2Wo&ithint=file,rar

Was the driver setup successful and you rebooted your computer afterwards?

I did install it and the file is there but I can't see anything about RST in my drivers... What should I be looking for?

also, I did restart the system after installing RST

A quote about all those terrible quotes:

Marty McFly: Whoa. This is heavy.
Dr. Emmett Brown: There's that word again. "Heavy." Why are things so heavy in the future? Is there a problem with the Earth's gravitational pull?

:wink11a:

 

[TomasD]

Could you also try disabling everything related to the C-States in your BIOS?

Haha sorry! I just quote because I assume it will give whoever is helping me a notification so they don't miss my latest reply

I've disabled C-states in BIOS and tried the game once again but there was still stuttering/volume fluctuations on my headset.

Is the fact that it only happens with external devices supposed to mean anything? I don't get this sound problem when using the monitor speakers but it has happened with wireless headphones/speaker connected via AUX cord/headphones connected via AUX cord.

I'm having the same problem on my fresh install of windows 10. I didn't have any problems on 8.1. I updated all drivers (including intel RST), the bios, and disabled c-states.

Intel i5 4460

I'm having the same problem...

Hi deltec and ohai! :smile9:
I think its better if you open a new topic for your problem, even if it's the same of this one.

:wave:

Didn't want to spam the forum without checking other threads first, so I posted here.
I will make my thread then. Thanks for the suggestion.

 

[xilolee]

Yes, that's correct... But given that this seems a complicated thread, it could become more complicated with three users (especially if the problem isn't already solved).:s1:

Do you think you could generate two new traces: one with using external audio (making sure you are experiencing the issues) and one with the regular speakers (no issues)?

 

[DarthVader]

Here is the trace using the monitor speakers (no sound distortion playing the Witcher 3): https://onedrive.live.com/redir?resid=D64E8DF2EC1DCB59!108&authkey=!AB640aXH_gAxwqk&ithint=file,rar

Will post the trace with external audio in a few minutes. Just need to generate it now.

EDIT: Here is my second trace using wireless speakers (PS4 Gold headset) that produced lots of sound distortion whilst play The Witcher 3: https://onedrive.live.com/redir?resid=D64E8DF2EC1DCB59!109&authkey=!AF-vgPqenwZt3qw&ithint=file,rar

Hopefully this helps you get to the bottom of things :)

Sorry, there does not seem to be a big difference between these two traces. There is a single NDIS.SYS spike on one of the traces, but it should not be related to using different audio devices.

I am starting to think the audio issues you are having might not even be related to DPC/ISR latency and might be related to your PS4 headset itself. You might want to contact PlayStation support for this.

It can't be the PS4 headset as I've used my bose mini speaker and a pair of sennheiser headphones which all produce the exact same type of audio stuttering whilst I play games. It must be something else

"guys its the intel network driver, anything past 19.1 will cause this issue, i use 18.5 with no issues, install intel driver 18.5 and your dpc latency spikes will go away!"

Using torrent clients or intense downloads make the problem appear more

I'm sure my network driver is qualcomm atheros wireless network adapter. I have a T-link adapter in my motherboard. Does that mean I don't have intel network drivers? I can't seem to find them.

Is no one able to help me with my problem? Such a shame :/ I thought we'd be able to get to the bottom of this. Seems like such a basic problem.
