Thanks Chuck! It was indeed a plugin-- NastyDelay, an older 32-bit tape delay simulator plugin. Weirdly, the problem disappeared when I deleted the plugin from the project, and then did not reappear (at least not yet!) when I reinstated it! Going to see if I can finish the mix as-is, and then abandon this one for the future! Thanks again for your help! It's always much appreciated.

Hello everyone! I have one particular project that is currently misbehaving--stutters, jitters etc-- but all else seems to be good. No jitter on other projects, no issues anywhere else, the LatencyMon utility says I'm good, only 12 percent drive access according to Cakewalk and 10 percent CPU... so, keeping in mind I've been through the weeds with troubleshooting this type of thing several times before...what's the most likely reason something like this would afflict one particular project? And how best to eliminate it? Thanks for your time! Win10 Scarlett 18i20 1st Gen

I'm indeed really greatful! Most likely I had a gradual sag/gradually less and less effective cooling unit through this whole process, hence part of the reason why I kept "solving" things for shorts amount of time-- cooling down while I ran diagnostics, shut things down/reset, etc. I had checked the temp a few times but apparently not often enough! Going to look into performance differences w/ more ventilation too...

Hello everyone! Okay, this appears to be solved for now... While trying to diagnose this Friday night, I popped up a diagnostic tool that displayed, among other things, CPU temp... and my CPU cores were at almost 100 Celcius! Quickly shut down and took a look at the fan assembly, which was badly sagging. Since the bracket was broken, and the other side of the motherboard inaccessible with this particular casing, took it down to a local repair shop today, where they replaced the entire fan/heat sink for me. So my intuition that this might be some kind of broader electrical or mechanical problem was correct. All seems well now! Thank you everyone very much for your help! I've learned a ton here and I'm going to continue checking out these diagnostic processes to see how much I can continue to improve performance going forward. Best, Sean

It's a wired network adapter. The problem has come back (albeit less severely) while the card is still deactivated. Is it possible I'm having some kind of electrical issue with my PC? I'm having a hard time figuring out why all of these issues would simultaneously come up. When the network card is disabled LatencyMon is now identifying Wdf0100.sys (a system file added by compulsory Win10 update last year) as the issue. I wonder if I'm heading for some kind of system failure and these performance spikes are the indicator. (Also tried running the command prompt system integrity diagnosis, which came back clean). Going to keep digging through the troubleshooting suggestions above. Thank you all again!

Well, that does it. It appears to be my Realtek network adapter driver. If I uninstall it my PC immediately passes the LatencyMon with flying colors. If I reinstall it, the doom sets in immediately. Well well well. Not sure what to do here. Disable or uninstall every time I run audio? Buy a new network adapter? edit: as indicated by the "processes" image above.

Okay, I've tried rolling back the update, reinstalling drivers, no dice so far. The LatencyMon suggestion however seems to be yielding some results, even if I can't interpret them myself. Anyone care to take a crack at it? Here's the text. "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 adaper, 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. [have already done so in BIOS, not sure where it is in Control Panel]. Check for BIOS updates. [There is a much more recent BIOS, going to try installing now] Here are screenshots of the Drivers and Processes page results. Would anyone kindly point me to what might be suggested by the results here?

Hello again Promidi! Thank you very much for your help. My videocard is the NVIDIA GeForce GT 635. Driver date 5/22/2019, driver version 26.21.14.3086 Yes, I've turned off the audio. Thank you for the suggestion re: the power handling of the card. Unfortunately it doesn't seem to have done anything with this particular problem. Any other ideas? I really appreciate everyone's suggestions!

Whatever the problem is seems to be making spikes in both of those, yes... I just tried disabling the Ethernet connection and the graphics card simultaneously, and there was no change, still there. Then tried uninstalling the graphics card entirely and resetting...and it went away! for about 5 minutes of playback. Then back to it exactly the same as before...

Here's a snapshot from the Task Manager CPU usage screen. Each of the "humps" is a pop/crackle etc. I don't know if it's because it has a slower refresh rate than CoreTemp, but the spikes LOOK much less severe here, but still visible each time https://ibb.co/7jg9zNQ The only visible CPU fluctuations via Task Manager are within CWBBL itself, all else zeroed out or close to.

Do you mean the Bandlab update? I'm not seeing other versions available in the Assistant interface...

Okay, I was enthusiastic too soon.... It's BACK! That seemed to be a temporary fix. Okay, I opened CoreTemp to see if maybe the issue was something related to my CPU. Temps look normal, and usage is at about 24 percent during playback, BUT on every crackle and pop there's a visible spike in CPU usage-- up to 36 or 40 percent. And then back down again. Somewhat rhythmical in nature. Anyone have any idea what might be going on here? Some background process grabbing CPU during playback??

Okay, believe it or not this was relatively painlessly SOLVED... by peeking at my post history on the previous forum! It's the insidious NVIDIA Audio driver, sprung back to life after the Windows Update! GRRRR. Here's the post: http://forum.cakewalk.com/Solved-Super-glitchy-playback-after-Bandlab-Reinstall-m3793399.aspx SO! If you have an NVIDIA video card, and you're having this issue, it might be an audio driver conflict. Check out the details at the previous post. Thanks for your help everyone!

Hello Cakewalkers! Just updated my Windows 10, and upgraded to the newest CWBBL and BLAss... and those dreaded clicks/pops/buzzes are back again. Super tight bottlenecked CPU-style behaviour but the CPU usage meter is reading around 20 percent. Seems to get worse when scrolling/graphic display is engaged. Any ideas? Anyone have a link to an updated version of that Win10 audio optimization guide that floated around on the previous version of the forum? Scarlett 18120 Gen 1 (up-to-date driver) latest CWBBL Win 10 latest Intel i7-4770 @3.4GHz 24 GB RAM NVIDIA graphics card Thanks for your help!

Very wise and generous advice, Tezza!
