toxify Posted June 23, 2015 Posted June 23, 2015 _________________________________________________________________________________________________________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 or more DPC routines that belong to a driver running in your system appear to be executing for too long. 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 0:02:50 (h:mm:ss) on processors 0,1,2 and 3. _________________________________________________________________________________________________________SYSTEM INFORMATION_________________________________________________________________________________________________________Computer name: TOXIFYOS version: Windows 8 , 6.2, build: 9200 (x64)Hardware: All Series, ASUS, ASUSTeK COMPUTER INC., MAXIMUS VII HEROCPU: GenuineIntel Intel® Core i7-4790K CPU @ 4.00GHzLogical processors: 8Processor groups: 1RAM: 8133 MB total _________________________________________________________________________________________________________CPU SPEED_________________________________________________________________________________________________________Reported CPU speed: 4007.0 MHzMeasured CPU speed: 4594.0 MHz (approx.) Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results. _________________________________________________________________________________________________________MEASURED INTERRUPT TO USER PROCESS LATENCIES_________________________________________________________________________________________________________The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event. Highest measured interrupt to process latency (µs): 596.165155Average measured interrupt to process latency (µs): 10.218542 Highest measured interrupt to DPC latency (µs): 589.460392Average measured interrupt to DPC latency (µs): 6.964764 _________________________________________________________________________________________________________ REPORTED ISRs_________________________________________________________________________________________________________Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal. Highest ISR routine execution time (µs): 465.782630Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Highest reported total ISR routine time (%): 0.079257Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Total time spent in ISRs (%) 0.155481 ISR count (execution time <250 µs): 216807ISR count (execution time 250-500 µs): 0ISR count (execution time 500-999 µs): 1ISR count (execution time 1000-1999 µs): 0ISR count (execution time 2000-3999 µs): 0ISR count (execution time >=4000 µs): 0 _________________________________________________________________________________________________________REPORTED DPCs_________________________________________________________________________________________________________DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

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. Check the Processes tab to see which programs were hit.

osRe Posted June 25, 2015 Posted June 25, 2015 I've no idea, but I can attest to seeing audio/video skips rather frequently. Even something simple like audio playback in Winamp is susceptible. No idea what's to blame.
toxify Posted June 25, 2015 Author Posted June 25, 2015 I've read countless page on google trying different things,can't solve it yet
toxify Posted June 25, 2015 Author Posted June 25, 2015 Your system info shows Windows 8 rather than 8.1?yep pretty strange cause when i pull up system properties it says windows 8.1 pro
osRe Posted June 26, 2015 Posted June 26, 2015 (edited) DPC Latency Checker doesn't really support Windows 8, so I guess it's a bug. It is that software, right? Edited June 26, 2015 by shae
cluberti Posted June 26, 2015 Posted June 26, 2015 I'll try to take a look at this in-depth later, but it appears your audio driver is a very likely culprit, CMUDAXP.SYS:
toxify Posted June 26, 2015 Author Posted June 26, 2015 i've tried it with the soundcard disabled and it still happens,plus i've also tried all the drivers available for this card none help
cluberti Posted June 26, 2015 Posted June 26, 2015 If that's the case (those listed routines call HDAUDIO functions, which would call the audio driver), then you have to start looking at both your video card drivers and your Intel ICH/RAID drivers. Both also have a decent number of interrupts as you can see in the table above. I noticed that the Intel Chipset is listed on IRQL16, as is your video card. Not good.
