Recently I've been having some problems playing back any sort of media. At regular intervals the audio will freeze/skip for a second and make a loud buzzing noise, then resume. This happens with both music and streaming videos. If I'm watching a video, the screen will freeze for a second, buzz, then resume.
I'm using an xps 13 9333 with Windows 8.1 64-bit.
I've tried everything I could think of, updating all my drivers, reinstalling codecs, running anti-virus, and cleaning out my system.
I have found a solution 2 days ago Dell installed an update for dell support assist and dell support agent When i removed these programs from the Control panel the problem went away.
I have windows 7 64 bit (dell XPS L720X).
Some background i originally had this problem two years ago and it was related to McAfee anti virus. My guess is its do to a periodic scan or something like that.
the only thing i uninstalled was dell support assist and dell support agent had to uninstall them both.
Uninstalling the Dell Support programs as you did should have automatically removed two system devices, Dell Diag Control Device (which is the culprit) and Dell System Analyzer Control Device. Go to the Device Manager (from the Control Panel) and look for these under System devices. If they are sill there, disable them; if not, then I don't know what to suggest, though
If you are familiar and comfortable with DPC latency detect and performance analysis software (I'm not), you should be able to isolate the problem (it's really easy to at least find dpclat.exe for free and run it to see if you are getting DPC spikes, which are the problem). I'm new to this Dell Forum, and I can't see that it's possible to put links into these postings (if it is, someone please tell me!). But search for the thread "Audio Stutters and Buzzing Caused by DPC Latency" on the SevenForums.com site; there you will get a good technical explanation of the problem (I'm assuming the underlying problem is the same in all cases) and some further good links to check out.
Randy, thank you SO much. Going into device manager and disabling those two devices worked !
I apologize for the inconvenience. Dell is aware of the problem and has a hotfix if you would like to continue to use Support Assist. You can find more on what Support Assist here on its community page.
Go here* Under the "End User" tab, click "SupportAssist for PCs and tablets"* Download/save the file "aulauncher.exe" to your windows desktop* Run the file* Reboot when done* Download/save the hotfix from this share* Double-click the exe file. You should get a message saying “Successfully applied the hotfix, please reboot your system for the changes to take effect”
Please let me know if you have any questions.

I've been trying to remedy this for weeks as some people said uninstalling this did not fix the audio/video problem.
What I did not realize was that delldatavault.exe runs as a service in the background. I discovered this while viewing my resource monitor and watching that particular service cause severe spikes in the CPU and disk activity which were the exact moments the interference in the audio/video would occur.
Completely disabling the service altogether, has finally relieved my migraine...
Thanks to ALL... I think the buzzing is finally gone... pretty much the answer is to uninstall or deactivate anything that has to do with Dell monitoring your computer... the final fix of disabling Dell Data Safe seems to have done the trick. I listened to a 5-1/2 minute song on YouTube without one buzzing interruption.
Randy, Thanks I have also been listening to that annoying interruption buzz for a few weeks. I found this thread and you made it easy to fix. Luke

Are you referring to Dell_Terry B's instructions?

stanshapBut it's not the Dell SupportAssist, because that's gone. Any more ideas ?
There are several other ideas in this thread in addition to removing Dell SupportAssist. I have summarized them in the Choppy/Skipping Audio FAQ.
Note that this thread and the solutions in it are about the noise issue that began right around Feb 11/12.
I'm having the same trouble with my XPS 15.It's annoying!
Have you also uninstalled some update from windows?
I was thinking that this could be related.
The only things different that i have installed in this period were the updates.
Anyway i'll try to uninstall Dell assistent.
Same here. I particularly experienced this when streaming movies and playing discs in my Bluray/DVD drive. And, as others have reported, I resolved it by removing the Dell Support Assist and corresponding Agent software. But, this is a FAR MORE TROUBLING SITUATION. Specifically, this software is SPYWARE published by Dell and pushed, without explicit permission, to Dell laptops and workstations, and if one checks the settings on this software, one will see the fine print next to an automatically (already) selected option. That fine print states that Dell has your permission, which Dell is implicitly giving themselves, to monitor essentially ALL communication and activity on your Dell computer! I initially tried to de-select the option, but the software automatically re-selected it. Also, I did not recognize this software on my system. It was only a few days later (yesterday and today) that I realized I was suddenly having these buzzing interruptions in my audio stream, with interrupted video at the same time, while playing / streaming movies, that I suspected the Dell software. So, tonight, I checked my installed programs and guess what I saw (it's worse than just the two programs mentioned thus far): Dell not only installed their new support assist and corresponding agent software, BUT DELL ALSO INSTALLED A CITRIX CLIENT, which means that Dell effectively gave themselves the ability to HACK my computer through remote control!!! This whole thing is BEYOND THE PALE and UTTERLY OUTRAGEOUS. This is not the sort of behavior I would expect from ANY reputable company on planet Earth. Dell needs to have its collective feet held to the public's fire over this! Needless to say, I also uninstalled the Citrix client. I would recommend to everyone who reads this that they remove the Citrix client as well as the two new Dell applications from their systems, AND, IF DELL REINSTALLS THEM SURREPTITIOUSLY, that you then REMOVE ALL DELL SOFTWARE from your Dell systems. This is by far the most egregious thing I've seen in a long time form Dell or any other company whose stuff I use. SHAME ON DELL!
Thank you, very much indeed.
I was having the same stuttering and lag with no CPU or RAM spikes, and I just spent 5 hours going insane trying to figure out if it was a driver issue or some incompatibility issue with a new SSD I just installed in my XPS13 L322X.
After uninstalling both of the Dell Support Assist programs, it's back to working perfectly again.
What an absolute farce that Dell would just install them, and break your machine in the process.
Thanks again for that, good advice to anyone reading with the same issue!
Thank you Wildmanyeah for posting your solution. I have included it in the Choppy/Skipping Audio FAQ in the XPS L702x section.
To others who post, if you would mention the full model name of your laptop I would like to put the solution in those sections of the FAQ too. What I mean is there are 4 different models in the XPS 15 series, and another 4 in the 13 series. Thanks.
I am SOOOO glad to see this post, I had feared that my XPS 13 started having audio issues just after the end of the 1 year warranty and that it might be hardware related. I knew I had just installed several updates from Dell, but none were directly sound related. Good to know it IS Dells fault!
Just to say I was getting the exact same problem (l502x). Many thanks for the answer - on a side note its not just when playing audio/video, the laptop actually hangs consistently, every minute, for 1 second. Obviously its just a lot more noticeable when you have audio playing.
I just think the problem should be addressed at Dell as obviously a lot of XPS users are going to have similar problems and may not be able to find this thread.
Just uninstalling the SupportAssist Agent seems to solve the problem. Dell Inspiron 17R SE.
I started having the issue today. I followed the advice of this thread and uninstalled dell support assist and dell support agent. Problem solved.
I didn't see any citrix client in my control panel. Can you provide a few more details?
Brilliant.. uninstalled dell support assist and dell support agent and my system is back to working perfectly fine.. thanks for the fix
My wif'e's Dell XPS 17 (L702x) had the same problem starting on Wed Feb-11-2015. Thanks for the great advice. Her problem was an occasional buzz, short, but annoying. I wonder sometimes about updates like this that are sneaked in without any notice.
Thanks a bunch. I would not have figured out this but for yours and the other posts here which supported the claim.
