Pausing/unpausing/scrubbing audio creates static crackles/pops
I can't figure this weird little issue out.
![]() I'm not sure how long this issue has been around on my PC because only recent situation made me aware of it. I was creating some SFX in audacity and I noticed any time I looped a specific type of audio there was a static pop/crackle at the end/start or during scrubbing, the SFX is a continuous droning bass loop to be used like a server humming etc, and any clip that ends or starts quiet doesn't seem to share this issue. I have tried updating my audio drivers, and video drivers, didn't fix it. I tested on speakers and also headphones, and in different jacks, crackles are on both, so it's deff coming from my PC, not faulty speakers. I tried most things in this help article that applied to my PC (minus updating BIOS drivers): Fix Audio Static Crackling Popping with Realtek Sound Card And just for a test, if you play this SFX (no DL, just play in browser), and pause/unpause during it, do you hear any static pops? or is it just my PC? lol Microsoft OneDrive - Access files anywhere. Create docs with free Office Online. I dunno what else to try to figure this out ![]() I'm happy to do any tests or provide screenshots to help diagnose this issue.

Set up a virtual machine with Linux Mint in the VM. Install Audacity in Linux. Try it in Audacity in Linux, to see if the problem persists there. If this is a Windows or a driver issue, it won't exist in Linux.

@fireberd is the go to guy for audio here,
I assume the audio you have is the onboard default system, I think this could be at least part of the issue as on-board sound is always a compromise between cost and performance, and the quality would be increased with an additional bespoke Audio card. Other thing to check is the placement of the power cables with relation to the audio components |

Is it safe to do this? I will give it a shot though, just don't wanna go messing around with the registry or stuff of that nature

I listened to the sample clip. I wouldn't call it "crackling" just sounds like a momentary dropout. Since it appears, from your post, to be what you are creating in Audacity I would suspect that is where the problem is generated and not really a problem with the PC audio.
Also, don't confuse the HDMI audio with the PC audio (Realtek). If you are not using HDMI audio it has no affect (and in most cases HDMI is generated in the video card separate from the PC audio such as Realtek). (I have a recording studio using Cakewalk Sonar and Studio One 3). |

Okay well I did think it could simply be that I made my SFX incorrectly, so I looked at other audio sources, but I still get the pop too, Eg: Forest Ambience Sounds, Sci Fi Insect and Fantasy Creature Sound Effects for Download - Exoplanet - YouTube pausing/unpausing also gives me the popping noises. Well my audio comes from my speakers being plugged in the normal jack at the back, I dont use HDMI for my audio, unless you mean something else (im obv a noob at audio just FYI lol) |

I don't get any pops/crackles etc on the YouTube audio so its back to your system.
Your system is similar to mine, ASUS ROG Z170 motherboard and an i7 6700K and Realtek sound. Download and run the free Resplendence Latency Mon. See what that shows. This program is very "picky" and has lots of data (I actually call it data overload) but it may show what is causing it. http://www.resplendence.com/latencymon |

One other thought, for testing. Uninstall Realtek in the Device Manager (and the drivers). Then restart the PC and Windows will (should) install the generic High Definition Audio driver. See what happens with this driver, again for testing.

So what do I do next? the suggestions it gives arent something Im familiar with doing on windows. And thanks mrjimphelps, I'll look into testing that if this current testing fails, cheers (edit) oh and heres the report it gave me: ____________________________________________________________________________________________________ _____ 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 problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup.

It is suggested that you run a utility which reports your actual CPU frequency and temperature. ____________________________________________________________________________________________________ _____ 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.
