    Uninstall, reinstall the Network Driver.

    You need to visit to the support site of the manufacturer to download and install the latest network driver which is compatible with your system and OS.

    Hi there,

    Crackling, popping, and other sound problems can occur for a variety of reasons. You may be able to fix the problem by adjusting your audio device settings, updating your sound driver, or pinning down another hardware device that's interfering. If a cable connection is loose, this could cause some sound problems.

    Also try steps as per this forum https://answers.microsoft.com/en-us/windows/forum/all/windows-10-crackling-audio/f495e9b8-8c43-492b-a88e-66e6b37cd7d9

    It's amazing that this problem has been windows persistant and microsoft only pulls it under the rug https://answers.microsoft.com/en-us/windows/forum/all/windows-10-high-dpc-latency-ndissys/fa49d3b5-82af-4d55-9c27-f3b3357619bd

    I had a native instruments audio 6 that got gliching thougt it happened because it was old and bought a presonus studio 24C and worked fine for a while two years and again its glitching specially when Im downloading something from Steam or the Epic or Xbox store and it's very annoying it started after a windows update and I'm not the only one who has this problems too also unsolved!

    They are the usual suspects wdf01000.sys and ndis.sys that DefragTools looks very useful and from 2015 you should have think that the audio latency problems have been fixed or at least asio implemented system wide multiple outputs from different audiocards with zero latency or something but here we are troubleshooting wdf01000.sys and ndis.sys problems since 2008
