harekowicz Posted May 11, 2013 Share Posted May 11, 2013 Hi! I do experience spikes and drops. Please help I have got DELL XPS 15. I've found out that ndis and usbport causes most troubles and I have already updated particular drivers but it seems it hasn't solved the problem.Here ia URL to my trace: My link Link to comment Share on other sites More sharing options...

monkey21 Posted May 11, 2013 Share Posted May 11, 2013 Hello, I've been having issues with audio playback skipping on this PC I've recently built, and I can't seem to solve it on my own so I'd like to ask for your help.I've Googled and tried pretty much every common solution, such as:Drivers: Have all the latest Chipset, audio and LAN drivers from the motherboard manufacturer's website. GPU is Radeon 68xx, and I've updated the drivers for that recently.BIOS: C-states, Speedstep and Turbo Boost are turned off. Everything else I don't use (integrated audio, USB 3.0 controller, serial port, etc.) are turned off as well. All power-saving options are disabled if possible.Windows: All power-saving options are disabled, the power scheme is set to High Performance. System sounds are off, processor scheduling is set to "background services". Most unnecessary Windows services and Aero are disabled, and the only non-Windows program I have on startup is Daemon Tools Lite.Other programs: No anti-virus running in the background, Windows Firewall is off as well.Some other things to note:-I'm running a USB audio DAC and the dropouts/skips only seem to occur with this device, the integrated audio chip seems to be working without problems. But the same DAC/setup works without problems on my laptop, so it doesn't seem to be a hardware problem.I've tried all the other USB ports on the motherboard, but they all have the same issue. I've read USB 3.0 ports could potentially have issues with audio playback, so I turned those off as I have no USB 3.0 devices anyway.-Disabling the (wired) network device in the Windows Device Manager temporarily doesn't solve the issue.-The problem seems to be with the "INTERRUPT TO USER PROCESS LATENCIES", which spikes to 1500-4000 sometimes, the ISR/DPC latency seems to be relatively low (below 200 µs), so I'm not sure how to interpret that, as from reading this thread, most people have an issue with high DPC.-The "hard page fault count" also builds up over time.Please let me know if you need more info, I've attached a screenshot and the log from LatencyMon below.Thank you!_________________________________________________________________________________________________________CONCLUSION_________________________________________________________________________________________________________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 problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. LatencyMon has been analyzing your system for 0:02:29 (h:mm:ss) on all processors._________________________________________________________________________________________________________SYSTEM INFORMATION_________________________________________________________________________________________________________Computer name: 123OS version: Windows 7 Service Pack 1, 6.1, build: 7601 (x64)Hardware: P67A-UD3-B3, Gigabyte Technology Co., Ltd.CPU: GenuineIntel Intel® Core i5-2500 CPU @ 3.30GHzLogical processors: 4Processor groups: 1RAM: 4079 MB total_________________________________________________________________________________________________________CPU SPEED_________________________________________________________________________________________________________Reported CPU speed: 3309,0 MHzMeasured CPU speed: 2158,0 MHz (approx.)Note: reported execution times may be calculated based on a fixed reported CPU speed.

The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops.

MagicAndre1981 Posted May 11, 2013 Author Share Posted May 11, 2013 @ monkey21run the xperf command and give me the file. Link to comment Share on other sites More sharing options...
monkey21 Posted May 12, 2013 Share Posted May 12, 2013 Hi Andre,I had the bright idea to check the components' manufacturers' websites for drivers rather than the latest ones my motherboard's manufacturer put up for download.So this might be worth a try for others who have tried "everything", try to find the model number of the component(s) that is giving you problems, and manually update the drivers.In my case I updated all the chipset drivers related to PCI bus and USB controllers, and also the drivers for my NIC.This seems to have fixed my issues; I occasionally still get a spike, but these are so rare I can live with it.Thanks anyway though, it's really rare to see someone so selflessly helpful nowadays!

3Seven Posted May 19, 2013 Share Posted May 19, 2013 (edited) Been having issues with erratic mouse behavior in game (negative acceleration and cursor pointing downward randomly) with 3 different mice in all games. I did a ton of hardware tests and came to the conclusion either my motherboard is faulty or i have driver conflicts.I also ran xperf while running Battlefield 3, but the file is huge and i'm having trouble interpreting the results. The tests seem to point to USBPORT.sys as the main culprit; i tried updating my drivers, re installing windows etc., but nothing worked.Any help would be greatly appreciated, thanks in advance!

MagicAndre1981 Posted May 19, 2013 Author Share Posted May 19, 2013 look for IRQ sharing. Which other devices share the IRQ of the USB controller? Link to comment Share on other sites More sharing options...
3Seven Posted May 19, 2013 Share Posted May 19, 2013 (edited) look for IRQ sharing. Which other devices share the IRQ of the USB controller?I only have 2 USB devices (mouse / keyboard) and they seem to be on: Intel 7 Series/C216 Chipset Family USB Enhanced Host Controller 1E26 - IRQ = 23Where i do see USB sharing is on IRQ 16. The devices sharing IRQ 16 are:1. Intel USB Enhanced Host Controller 1E2D2. Intel PCI Express Root Port 1 1E103. Intel PCI Express Root Port 5 1E184. Intel Management Engine Interface5. Xeon Processor PCI Express Root Port 0151PC's a new build ~ 3 months old, worked fine for a month or so.

MagicAndre1981 Posted May 20, 2013 Author Share Posted May 20, 2013 the ETL show no issues. The DPC and ISR values don't reach the 1024µs. Connect the mouse to a different USB port. Link to comment Share on other sites More sharing options...
3Seven Posted May 20, 2013 Share Posted May 20, 2013 the ETL show no issues. The DPC and ISR values don't reach the 1024µs. Connect the mouse to a different USB port.That's weird, i've tried plugging all 3 of my mice to every port with the same erratic mouse behavior, guess my issue is related to something else then.Like i said, worked fine for a month before problem started. Thanks for the help, i appreciate it. Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted May 20, 2013 Author Share Posted May 20, 2013 do you use a generic mouse driver or a specific driver from the vendor? Link to comment Share on other sites More sharing options...
3Seven Posted May 20, 2013 Share Posted May 20, 2013 (edited) do you use a generic mouse driver or a specific driver from the vendor?I've tried it both ways; before i re-installed windows i used the vendors, when the issue appeared the very first thing i did was uninstall them and try the generic MS drivers only.It's funny that the etl shows no issue while Latencymon tells me otherwise. Would the etl show if the issue stems from a faulty motherboard? I've tested every piece of hardware i have, but have no idea how to go about testing my motherboard itself or it's I/O Ports.Edit: I had found two threads while researching my problem where one was resolved by disabling all power saving features in BIOS and Windows (didn't work for me) and the other could only get rid of the negative acceleration by buying a new motherboard altogether.
