    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:

    Audio stuttering/buzzing and storport.sys high dpc latency

    I've only had this audio issue for a few weeks already after I did a custom windows 10 install bc of a previous problem. I've also posted twice about this but no one has helped me yet. I'll post the following possible solutions and suggestions that
    I've already done to avoid repeated answers

    I did: audio troubleshooter, uninstalled then reinstalled audio drivers, disabled audio enhancements and tried different audio quality under the advanced tab.


    After more searching online I tried using DPC Latency Checker (and then LatencyMon to be more detailed) since I read that having high dpc latency can cause problems with real time audio among other things. Apparently
    storport.sys is the problem? I literally just have basic knowledge about anything regarding this kind of stuff and I don't have any clue on how to fix this so I just hope someone can help me and give me steps by steps suggestions on how I can solve this. my
    audio has just been driving me crazy with those stuttering sounds and I don't want it to worsen.

    I would also like to know if having
    Ricoh SD/MMC Host Controller     and nothing else aside from that, under
    IDE ATA/ATAPI controllers    , is okay and won't cause problems?

    please, I hope someone can help and answer this time around!
