PC Latency problem

[martblek]

So I really don’t know how to deal with it anymore.
After the total necessary reinstallation of Win, I am not able to render sound without having some sound artifacts. This is not only about Renoise, but in general, even when listening. I tried different drivers but still nothing. I tried the recommended things, turned off the services but still nothing
Any idea ?

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. 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. 
LatencyMon has been analyzing your system for  0:35:53  (h:mm:ss) on all processors.

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.

Highest measured interrupt to process latency (µs):   13915,0
Average measured interrupt to process latency (µs):   7,872703

Highest measured interrupt to DPC latency (µs):       742,60
Average measured interrupt to DPC latency (µs):       3,053947


_________________________________________________________________________________________________________
 REPORTED ISRs

signal.

REPORTED DPCs
_________________________________________________________________________________________________________

while it is interrupted until the DPC has finished execution.

 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.

Process with highest pagefault count:                 firefox.exe

Total number of hard pagefaults                       26438
Hard pagefault count of hardest hit process:          3095
Number of processes hit:                              100

Is this usb audio? In older days, a fix was to re-sort/exchange the pci-e cards, so the interrupts are used differently. Or try another USB port which is using a different hub.

Maybe:
https://support.microsoft.com/en-us/topic/how-to-disable-pci-bus-irq-steering-in-windows-695c360f-1aae-471e-878e-07ff971b8e02

Or have a look into your bios options.

[eretsua]

I’m sure you’ve tried this, but does the problem occur with WASAPI, ASIO and DirectSound?

Also (re-)check the buffer settings of your audio interface. Sometimes they default to weird values.

And then the usual stuff: if it’s a USB interface, try switching USB ports, USB cables and disconnecting all other USB devices.

Depending on your make & model, you audio interface may be supported by something like Linux Mint of Ubuntu. Make a portable version of it on a USB stick and boot into that. See if you have the same problems it’s maybe a hardware issue. But if it works normally there it’s probably a configuration issue in Windows.

[martblek]

This is happen after clean reinstall win11. On linux is all O.K.
In win i tried original ASIO Behringer drivers for my UPhoria UMD404HD, I tried Asio4All drivers.
This is happen on ASIO, WASAPI and other drivers. No way to escape
I look at these IRQs.

this is my problem

[ffx]

Yeah most likely the IRQ now is shared with a heavy device like GFX (so in theory also the gfx driver could have an influence)… So this is USB audio? Try those options mentioned in the link above. Also look at the bios’ irq page. Maybe there is a reset option or so, too?

[shorty]

I had this too, after a fresh Windows 11 install. Changing the external USB audio interface to another USB port solved it for me.

[martblek]

No settings for IRQ in bios.
I set in processes CPU 4 an 5 to audio and switched USB ports.
Now is max latency 1905,5 us. But this is better than 18000.
We will see. Thanks for tips.

My sound card was in one port for 2 years and suddenly after the update should I move it somewhere else?
They should probably write that after every reinstallation we have to connect everything. If I don’t prefer to swap the disks on the Raid field too.

OOPS now is 4k and growing

[ffx]

Also no options in BIOS like:

Reset Configuration Data
Resources Controlled By stellen Sie auf Auto oder ESCD
PNP OS Installed

? Under PnP/PCI Con­fi­gu­ration or so?

[martblek]

No. Just load defaults.

[martblek]

After an hour.
Now it is much better.
Thanks this.

[James_Britt (James Britt / Neurogami)]

Please don’t say you fixed it without explaining what you did.

Other people with the same issue will find this post and want to know.

[eretsua]

Martblek did say what was used to fix the issue:

@martblek

Thanks this.

Antilag, Which is some kind of system optimizer tool, by the looks of things. I’m glad it worked out for Martblek. But yeah, a detailed list of what settings the tool changed would be great.

[martblek]

Hello,
I don’t know what changes. There is only an .exe file on the website.
I know it’s a risk, but it helped.
I’m not a Windows expert and searching the registries is hell. In my opinion, it changes the power settings for the CPU, usb, etc., no stupid eco mod, everything works fine and without putting to sleep.
I also turned off the services and drivers that I don’t use and especially the high precision timer, realtek audio and so on.

It’s still not as good as on linux but it’s better than a wire in the eye

[eretsua]

That link was already there before your message appeared on my screen. I had already followed it. And I don’t see an orange pencil indicating that his post has been edited. Not that it matters, of course.
