Question Audio cracking, sound cutting out

Oct 11, 2019
Hello, i upgraded SSD, installed a fresh copy of windows with new key and all, installed a new motherboard and now i got audio cracking and cutting out, ive tried updating and downdating drivers without any luck, tho im not100% sure which i need to, updated chipst, sound, graphics and network and the ssd too, i got lead to this program which should help troubleshoot and it seems it has for alot, so im hoping someone can help me figure it out, heres the info it gave me


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. Also one or more ISR 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.
LatencyMon has been analyzing your system for 0:08:57 (h🇲🇲ss) on all processors.

Computer name: DESKTOP-COSNP4D
OS version: Windows 10 , 10.0, version 1903, build: 18362 (x64)
CPU: GenuineIntel Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz
Logical processors: 8
Processor groups: 1
RAM: 8126 MB total

Reported CPU speed: 4008 MHz

Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

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): 5436,60
Average measured interrupt to process latency (µs): 6,533270

Highest measured interrupt to DPC latency (µs): 5389,30
Average measured interrupt to DPC latency (µs): 2,691382

Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

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: chrome.exe

Number of processes hit: 19

im using realtek, or well, realtek is what i want to use, but a csgo awp(sniper) shot(more or less like a real like sniper) sounds like a arcade tank with it, so im using my nvidia atm which seems to be working fine, but i cant get any kind of 3d sounds from it

it seems to be cutting out alot more often when i download and install stuff
I have the same problem, occurs when the PC is working hard or trying to multi-task and feels to me like wear and tear relating to the motherboard which i'm replacing as I read somewhere this can be a motherboard issue.

i read somewhere it said that some motherboard just are like so, and i kinda went with it, but then i noticed tiny cuts in sound on my nvidia audio whenever -and i also noticed- latencymon spiked, which suggests some issue that should be able to affect sound in such a way to make a csgo awp shot sound like a arcade tank/fireworks, so i´d like to give my best shot at fixing it

Ok so go in to bios and disable all power saving settings for pc and cpu. Try installing an earlier Nvidia driver like 431.36 that was the most stable one I can remember. Can you go to device manager and under audio game controllers etc, click on that and post what it says for sub menu. While you are there just check to see if the drivers can/need to be updated for the audio items.
