BT, Shiny new interface. Sure. Can you make us happy, temporarily disable Ethernet adapter, put computer in airplane mode and try to fish for a glitch one more time?
There might be a piece of software that is "sending statistics" or similar that is causing this. You went pretty far. These are peanuts. (But very well could be the culprit)
Didn't take long to catch this "fish"; less than 2 minutes. Studio One was playing.

Thanks. If it stayed that way for twenty minutes, that’s very good performance and rules out several things. But let it run for awhile and see if you get any red spikes.

BT, pulling cable will not solve, I believe temporarily disabling adapter will.
You didn't explain. How do I disable the adapter?

I am on WiFi, but I guess the process for wired is same (if I remember correctly) Click on connection at lower right corner and just click once on whatever you are connected to. (blue color tile, which would become gray when you click on it to disable)

Now I get the large latency when NO music is playing.

Where you lost me is "connect the mixer output to your computer audio in".
BassThumper, What I'm suggesting is you should be able to send the audio output from the six channel mixer to the onboard audio (Realtek) connector on your computer motherboard. Others have suggested using YouTube as the audio source and the Realtek to send the audio to your headphones or speakers. I'm suggesting the same just using your mixer instead of audio already on the computer.
As a minimum the back side of your computer should have connections for audio in and audio out. Depending on your Dell computer motherboard they should be 3.5 mm color coded connectors similar to a connector you would plug a set of wired headphones to.
What is the model number of your Dell computer? I can download the manual and mark up a photo of the rear panel of your computer.
To disable internet I would Go to Control Panel Click Network & Sharing Click Change Adapter settings (which displays all network adapters)
Right click any active one and select Disable After testing you could simply right-click and Enable to return.
Have you yet eliminated the USB cable? I'm telling you, as a guy who works with PCs every day, I was surprised that one thing fixed issues that I had been 'fishing' for a week or so with lots of frustration.
I'm not saying it is the answer for sure, but it was a surprise to me when all the issues went away with the new cable. My problems appeared random like yours and I was convinced it was system related .. but it wasn't in my case. Just trying to help and you can feel free to blame me if it doesn't work.
I do not work here, but the benefits are still awesome Make your sound your own!

Thanks of the info rharv.
Regarding the USB cable. The new one still hasn't arrived from Amazon. But when it does it will be immediately installed. And there is never any blame if that idea (or any other) doesn't work. This is a tough nut to crack and I appreciate all ideas.
The DPC Latency Checker seemingly is a good piece of software but the process of hunting down the software responsible for the latency is a painstakingly tedious process. You have to watch the thing as it scrolls by second by second to determine if you have a glitch. Then you guess which software you should disable and repeat the process until the culprit is identified. The next time I talk to Dell I'll ask if they have a more automated diagnostic tool.
In the meantime, if anyone has a contact at Thesycon GmbH please suggest the next update latches/captures the error flag so that you can run it, walk away and return in an hour confident that if an error ocurred you have it captured. Of course, the "holy grail" would be, in addition to capturing the error flag, to tell you the specific sw that caused the error. I would think audio engineers and musicians around the world would find something like that useful.

If Dell has such a tool, I hope you will be able to share it. As for DPC Latency Checker, it hasn’t been updated to read accurately in Windows 11, so it may be end of life.
As for hunting down the cause, this guide from Sweetwater will give you what you asked for. Causes of DPC Latency and How to Fix Them Article #1771015 Updated on Sep 21, 2022 at 1:41 PM
After much research, trial and error and old fashioned hard work I think I solved this crackle and noise problem.
I want to thank all those in this forum that contributed to the overwhelming flood of ideas and things to try. I also received many ideas from people at Dell and Tascam. This was one tough nut to crack that stumped some very smart people. At each step along the way I tried to manage the troubleshooting process by exploring the lowest hanging and most risk-free fruit.
Someone in this thread mentioned getting rid of the “crapware” and that idea resonated with me so I simply uninstalled the Dell SupportAssist software as a stab in the dark. So far, this seems to have solved the problem. Over the last few days I’ve accumulated approx. 2 hours of crackle-free music. And today I got Dell Tech Support back on the phone and shared my progress; he wasn’t overly surprised and said that their software runs continuously in the background and could be the root cause of the noise. I pointed out that there were several other Dell applications loaded on my machine. We decided to uninstall them all one by one. These were
Dell Digital Delivery Services Dell SupportAssist OS Recovery Plugin for Dell Updates Dell SupportAssist Remediation Dell Update for Windows Universal
In addition to learning a lot about PC technology, I also (re)learned that perseverance can really pay off.
My plan is to observe my system for a few more days and then re-enable Intel Speedstep. For good measure I also plan to install my new USB cable and apply a bit of DeoxIT to the connectors.
I showed the Dell guy LatencyMon and DPC Latency Checker and asked if Dell had any such tools. He said he was unaware of any. This tells me that there are areas of computer technology where we, in this forum, are more sophisticated and advanced than Dell tech support people.
Moral of the story: If you really don’t need a software program, uninstall it. It may be crapware hiding in full sight.
Thanks again to all those that helped.

Steve, Fingers crossed. Telemetry, data usage, location and all those other wonderful spying, pinging, sending data "tools" which are pre installed by default on "reputable" brand machines is not a joke. Especially when resources are being sabotaged.
There are some tools I have tried in the past to stop computer sending out data... One stands out. It was called Shut Up Windows. It got renamed, but should come up in the search. Just make a note of it. Might come handy one day.

Very well spoken.
Another Dell disappointment was their inability to explain how their software corrupted my audio signal chain. I specifically pointed them to my diagram shown in post #762527. They couldn't even offer any additional detail to the diagram much less tell me if the CPU, buffer, D to A conversion or something else is being stepped on by their software.
I'm learning that although as a company they may be good at assembling the various components into a working computer system, the people available to me at Dell are simply not able to address the critical technical questions of why and how.
I'm squaring this circle with this analogy. If you want to know why the rocket blew up on the launch pad, you can't just ask the guy on the factory floor; you need to engage with the chief engineer and his people.
I have no doubt that the "factory floor people" at Dell did their level best to help me; they simply are not sufficiently trained to be of much use in solving the problem I posed to them or explaining the why's and how's after I solved/improved the problem for them.

That's freaking awesome!! I feel bad for not saying something on that topic since I'm a Dell guy too. I was troubleshooting a non-audio issue about a month ago and installed SupportAssist to get all my drivers updated and further troubleshooting. Once I was all good I had to end up uninstalling all that same Dell stuff as it was consuming a lot of resources just to run in the background. It was pretty much the same list you posted.
I'm so glad you got it sorted. Nothing like an annoying issue to keep you down. You persisted and got it.

I'm glad that you are up and running without any problems. Stuff running in the background can cause a lot of problems for us musicians.
Probably the reason the Dell tech guys didn't know about the cause is because making music with a computer is the smallest common denominator of all computer uses. I have read where the next smallest is photography and it is 4-5 times larger than recording music.
My boss calls me "the computer". Nothing to do with intelligence. I go to sleep if left unattended for 15 minutes.
