Windows 10: DPC routines executed too long. Audio either stutters and wont stop or cuts out completely

Hey, for the last few months when using my PC ive been having DPC issues and nothing ive found online has helped. It first started with the audio stuttering and then it would just continue to stutter over a second loop until I unplugged my audio interface focusrite 4i4 3rd gen and then plugged it back in which would fix it. Now when these glitches happen, instead of the audio stuttering, it just straight cuts to silence, again, unplugging my interface and putting it back in solves the issue. When running Latencymon it says my DPC routines executed too long but I'm not sure what this means or

:)

 

DPC routines executed too long. Popping and clicking sound.

Hello, I am having a issue where anytime I open a game I get these random stutters where my fps drops to 1 fps and my screen freezes I also get audio cutouts, I don't remember this happening when I first bought my laptop but about 2-3 months ago I started noticing this very annoying issue, I have tried a lot of things like changing my power supply to 100% so my cpu is getting 100% and also I have tried updating all my drivers, the problem is still here. Please help me fix this issue. Here are some results from latency mon:

CONCLUSION

_________________________________________________________________________________________________________

Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

MEASURED INTERRUPT TO USER PROCESS LATENCIES

_________________________________________________________________________________________________________

The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. 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.

REPORTED HARD PAGEFAULTS

_________________________________________________________________________________________________________

Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.



NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing
for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS
setup. Check for BIOS updates.

Audio driver conflict causing stuttering?

Hi All,

I've been having an issue for months now, appreciate if anyone could help me out.

My PC tends to stutter at random. FPS in games remain constant 60-40 but audio crackles and the display lags. As far as I can tell, the stuttering is random as CPU/GPU/Memory never hit 100% for the stuttering to trigger. I've checked hard pagefaults as well
and my counts seem normal. Temp are normal as well.

This is a fresh install of Windows 10. The problem was persistent before, I had though that upgrading to an SSD whilst migrating to a fresh install would get rid of the problem. The drivers for each were the latest I could get from their respective websites
as far as I can tell.

Specs:

Some clues:

LatencyMon tells me that the highest DPC is coming from storport.sys.

I have a strong hunch that there's some conflict between Nvidia HD Audio and Realtek HD Audio drivers. Disabling one or both of the drivers tends to get rid of the stuttering. Nvidia HD Audio driver reinstalls itself though. I've reinstalled my Nvidia drivers,
cleaning out using the DDU and deselecting the audio drivers on installation. Appreciate any advice on this, thanks!
