Audio dropouts/pops and DPC Latency W10 Home

Hi, I checked Dell Update that day you sent the forum post and just a few minutes ago too. No update from Dell side.

Either case, I haven't really been able catch both mouse and keyboard at the same time because usually in less than half a second, the freeze ends and I would not have had the time to check anything else. However, in the few traces that I captured the past week, I had my earphones in my ears (no music, I was playing some videos which ended while I was typing). But there was some white noise in the background when the glitch occurred.
2 instances were caught in traces when I was typing with my laptop keyboard (trace 1 and 2), and 2 more instances were caught in traces when I was using an external USB keyboard (traces 3 and 4).

There are newer updates available on the device support site. Perhaps Dell haven't got around to updating the support app or have possibly abandoned it for your device - it wouldn't be the first time. I'd suggest going to that page, clicking the "Show urgent downloads only" switch to filter the list, and then manually download those marked "Urgent". I'd then install them all one at time followed by a reboot. At the very least there's a newer BIOS and also an updated Killer Networking installer. After downloading all of the the urgent installation packages and prior to installing the Killer Networking drivers I'd uninstall the Killer Performance Suite from "Apps & Features" followed by a reboot.

As far as I can tell from the traces it looks to be Windows or Intel drivers that are taking so much time. Hopefully addressing the above will update those drivers and possibly fix the issue. Please try it and then test the system by trying to recreate the problem. If the problem continues I'll need to see what drivers are loading and look at event logs so you'll need to run the Sysnative Collection App to gather that information and attach the zip it generates to a reply. Steps 1 and 2 here detail how to do so.
 
I have a Dell G5 and I'm experiencing the same problems. Dropouts every 20 minutes or so with an external sound interface, only when I was connected to the internet.

I believe I've fixed the issue by disabling or stopping most of the Dell services and applications, as well as something called PC-Doctor. I'm no computer expert so I don't know what I did, but I haven't had any dropout for more than 24h so far.

I still get one or two pops but only over long periods. I'm using Cakewalk and a Focusrite 4i4.
 
Updated the drivers and still had quite a few instances of freezes/stutters/audio pops.

Trace 7 and 8 had mouse stutters - wasn't able to capture anything else along with it.
Trace 9 was a full screen freeze - keyboard wasn't responding, mouse wasn't moving, and even the cursor on the word document wasn't blinking (I suspect this was more than just a case of DPC latency)
Trace 10 was more mouse stuttering.
There is another trace called traceLiveMusic, which I recorded during a live performance setting. Meaning, it happened when I was using Ableton and sound going out through an audio interface. There were 2 major audio drop outs, where the sound completely stopped for a full second before coming back. Both dropouts were caught in the same trace (one quite early on in the trace, one somewhere in the middle), as I couldn't stop to end traces after the dropouts happened.
 
The link you posted in #24 is prompting me for login credentials. Can you change it to behave the same as your other links?
 
The new traces suggest to me the computer is still having issues that are generating live kernel dumps. I'm fairly certain trace09 shows a LKD being generated as all of the cores have been halted for around 16 seconds while something is going on. My guess is it was writing the contents of memory to a LKD. The other dumps mostly show long DPCs involving Microsoft USB drivers. I'd be looking at event logs rather than traces to try and figure out what's going wrong at this point. Have you looked at Reliability Monitor to see if any errors correspond to the hangs and glitches?
