  1. High DPC latency causing audio pops


    Since I bought my laptop I can hear random popping sounds while playing a Youtube video, it doesn't happen frequently so I decided to let it pass. Some days ago I decided to get to the root of the problem and I found it was due to a high DPC latency.I have updated my drivers and my BIOS is updated too. I have tried literally everything in power management. I have disabled and enabled intel turbo boost and c-states, nothing works

  2. High DPC latency causing audio stutters

    Quite different hardware but this may have your attention.

    Sound artifacts and high DPC latency seemingly related to storport driver can be caused by switching between Cx power saving processor states. My pci-express add-on soundcard works correctly only if C states greater than C1 are disabled:

    If you want to give it a try, see your mobo manual:

    Does Latency Mon show hard page faults (and what device)?
    That seems to be the biggest item.
    Run Latency Mon and the post the overall screen (mine is shown below).
