    High DPC Latency/External sound interfeace problems

    Hi everyone,

    First of all i'm italian so forgive me for my english.

    So i've recently bought a new laptop, an Asus Vivobook Pro. Intel i7 7700HQ,16gb Ram DDR4, 512gbSSD+ 1Tb Hdd and a Nvidia GTX 1050.

    I bought it for music production. I use a Focusrite Suffire 6 Usb.

    Since the beginning i had problem with my audio interface. When i recorded it crashed after 10 seconds, and even if i played an audio file.

    After contacting the assistence the suggested me to do a latency test, and i found out that there was an high latency. So i thought that was my audio intefece's fault, but also running the test with the sound card disconnected there still was an high latency. I tried to disconnect the wifi, and found out that there was less latency,but still to much. I read on latency mon's result that one of the driver that has more latency is HDAudbus.sys and the other one in wdf0100.sys. Whene i run the test with the wifi on the driver with the highest latency was the ndis.sys which i suppose is related to the wifi.Indeed when i turn off the wifi the sound interface doesn't crush and there are no crackels or anything. I updated the drivers of the intel dual band wirless, but still there is the problem. I'd use the Focusrite without Wifi, but still there is the problem that there is an high latenecy even if i don't connect both the sound card and the wifi. So i'd like to solve the problem.( i've already tried to change the power saving setting,and set them to High Performance)

    Following you'll find the LatencyMon results, the one with no wifi.

    I hope that someone can help me, let me know if you need further information.

    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. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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 0:01:19 (h:mm:ss) on all processors.

    Reported CPU speed: 2808 MHz


    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 (Ás): 4043,857013
    Average measured interrupt to process latency (Ás): 4,095642


    Highest measured interrupt to DPC latency (Ás): 2405,746660
    Average measured interrupt to DPC latency (Ás): 1,456750




    _________________________________________________________________________________________________________
    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 (Ás): 1603,131410
    Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation


    Highest reported total ISR routine time (%): 0,034938

    _________________________________________________________________________________________________________
    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.


    Highest DPC routine execution time (Ás): 2374,058048
    Driver with highest DPC routine execution time: Wdf01000.sys - Runtime framework driver modalitÓ kernel, Microsoft Corporation

    _________________________________________________________________________________________________________
    REPORTED HARD PAGEFAULTS
    _________________________________________________________________________________________________________
    Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.




    Process with highest pagefault count: none


    Total number of hard pagefaults 0
    Hard pagefault count of hardest hit process: 0

    Re: High DPC Latency/External sound interfeace problems

    I did it.

    Here is the dropbox link for the zip file containing trace.etl, msinfo32.nfo and DxDiag.txt : Dropbox - Results.zip

    Here's the link of the speccy test: http://speccy.piriform.com/results/Y...nVw6OOzpTd4ocJ

    Thank you

    Re: High DPC Latency/External sound interfeace problems

    Can't find the support page of ASUS for your laptop model.

    Check for Intel chipset (or Rapid Storage Technology) and NVIDIA display driver updates.

    Re: High DPC Latency/External sound interfeace problems

    I'll do that.

    Anyway i've both an onboard graphic card an Intel 630HD Graphics , plus a dedicated one, the GTX1050. Can this influence anything?

    Re: High DPC Latency/External sound interfeace problems

    Not per se, if you have configured to use either with certain programs.
