XPS 8950, "hiccups" with audio and video

I must say my XPS 8950 with i9, 32 RAM, and the 3060 Ti GPU, has been great for audio recording and video editing.  However, when playing audio, either with my software or a media player, or watching a YouTube, the computer will "pause" for a split second, usually with a white screen "flash" and then continue on. All latest drivers, bios, etc

Obviously for casual YouTube, etc, it's not an issue. Live audio recording or video screen captures, it is. I'm using a Windows 11 approved external sound card and two monitors with the 3060 Ti.  This might occur every 20 minutes or so.

Where might I troubleshoot first?

Hi all -- I was experiencing this issue in July. There was a spike in latency exactly every 15 minutes (literally every 15 minutes).

 


Thanks for the report on Uninstalling Support Assist, as that should help some people finding there way here:

We have seen that for a while now over the years. Seems it's depended on various Processes and Services and tends to get overly-needy as it tries to monitor everything.

In another thread, we came across this other software causing Latency or communication problems over USB/Networking ports. Since I think some of yall use external audio interfaces, I thought it might be a helpful troubleshooting step here.

From my notes:

I've found that you can simply uninstall Intel Killer Performance Suite from Control-Panel/Programs-Features, and then reboot . I found that all the Killer/xTend Services were also properly uninstalled (but you should probably double-check for lingering Services anyway). The base ethernet Network Interface Card drivers are left in place and the NIC still works fine (actually, usually better than before as it's a leaner/simpler configuration).

Any luck... I'm having the same issues with the same computer and the same software

I'm also having disaterous incidents of DPC Latency. And I do believe it's related to the  NVIDIA GeForce  RTX 3060.  How did you get rid of the NVIDIA control panel?

I am getting the same issues here as well with a Dell XPS 8050 , So did you mean to uninstall all three "Dell SupportAssists"?  There's Support Assist,  then SupportAssist OS recovery plugin for Dell update,  and  lastly there's SupportAssist Remediation.  Should I uninstall all three?  Thanks. This issue has been driving me crazy since July 2022. Maybe even June.

Just Support Assist. I still have SupportAssist OS recovery plugin for Dell update and SupportAssist Remediation.

I'd uninstall everything related to SupportAssist (and Killer internet).

Has anyone tried using Process Explorer (free from Microsoft) to see if it can ID the specific process(es) causing the excessive Interrupts and DPCs

Launch PE and select Options>Always on top. Make the window small and put it off in a corner of the screen. When you notice lags, look in the PE window to see if it can ID the specific process...

No. Please look elsewhere (lots of good tips in this thread and others here).

No, don't get rid of the Nvidia-CP either (you need it).

Remember, many use Nvidia RTX-3060 and similar cards for VR, gaming, and other low-latency uses.

I'm not sure if I'm replying to the correct spot but I have had some luck as of yesterday. I'm still running the pc through it's paces to make sure but I have had 2 hours of no spikes in latencymon and no crackles, or stutter of any kind. Here is what I've done after all the fixes and tweaks so far.  I recieved an e-mail this morning from Dell Technical Updates. I have it sent regularly. This morning they sent this update. I think it's a BIOS update. For more than 2 hours, I've been DPC latency free. This was the name of the Update.    Dell-Update-Windows-Universal-Application_0RCG0_WIN_4.8.0_A00.EXE It was on the page  - Dell Update Windows Universal Application - I'm not sure how to point you thtere because it's not on the usual driver update page. Let's see if someone else has success.
