Windows 10: Cant get rid of latency/crackles, Latency monitor report enclosed

Hi all, apologies for the length, trying to enclose as much info as possible.

I have an external firewire audio interface that I use with music keyboard and various music software.
Having problems with latency. It sounds like a static type crackle, cant seem to get to the root of the cause. Doesn't matter if I'm listening through my monitors or my headphones (both plugged into my Pro24).

It doesn't matter if I set my ASIO buffer low or high, sure if I set it to 2048 there's a noticeable wait between me pressing the key and the sound playing, but whether I set it to 2048 or I set it to just 32. the crackle still keeps appearing *Sad

Running Latency monitor shows problems. Please see attached text file and pics

Before I ran it this time, I unplugged my Focusrite Pro24 firewire lead, I went into the BIOS and disabled the firewire port. I exited out of malewarebytes, mouse software etc etc etc. Only thing I left running was Avast, but I disabled all shields until next reboot.

Getting exactly the same result as when the pro24 was plugged in and enabled, and when I left all software running.Sometimes I can play just 2 or 3 notes before it does it, other times it does it after about a min or more. I've been putting up with it for months, but really want to get to the bottom of it.

High latency and stuttering/crackling/glitching audio with wireless traffic on Dell Inspiron N5110

Whenever I try to watch a movie (especially from a network share, but also on Netflix or other streaming websites) I will get random glitches/buzzes/crackles. They are related to latency, NOT audio hardware. The only solution is to use "high performance"
power plan which seems to eliminate the crackles and reduce the ndis.sys latency from 30ms to 5-10ms, but I'm not a fan of this solution because it increases heat and power consumption. There has to be a better way, or at least I would like to find out why
this is happening. This was never a problem on Win7 as far as I remember.

The main suspect is my wireless card Intel Centrino N 1030. If I connect ethernet cable, the whole crackling problem seems to be completely gone, no matter what power plan I use, balanced or high performance. But when using wireless audio glitches come back
and, it shows up to 30ms DPC latency on LatencyMon, which is very high. I have the newest driver from Intel. That being said, I still think it may be something else and wireless may just be the straw that broke the camel's back especially because I can't really
find any reports on the internet regarding N 1030 latency issues.

Before you ask, I have updated all the other drivers to the newest available and that didn't help. I've tried various fixes suggested by others, like reinstalling windows, and so on, but nothing helps. Previously, I had Win10, but the problem with audio
and stuttering was so bad that I had to downgrade to Win8.1, which is A LOT better.

I've even tried bdcedit disabledynamictick, but that didn't help either.

LatencyMon reports high interrupt to process latency, so as far as I understand it, the ndis.sys (wireless) DPC count may be simply reflecting the fact that the CPU is not responding on time or is busy with something else for some reason. Can someone help
me figure out what's going on?

 

Windows 10 High Dpc Latency

Care to be more specific about the problem instead of pasting useless latency monitor data.

You are on win 8. You need to update to win 8.1 and by itself that may fix the problem.

Ar you overclocking?

Latency Mon is reporting your CPU as the following

CPU SPEED

_________________________________________________________________________________________________________

Reported CPU speed: 40 MHz

Measured CPU speed: 17 MHz (approx.)

Obviously this is wrong. You have an i7 Clocked at 4 Gigahertz. Why would you believe anything else latency mon says.
