High DPC latency causing audio stutters Solved

    Maybe it is time to start from scratch. What you can do:

    - remove all unnecessary hardware including graphics card
    - reset bios/uefi settings to default
    - install some linux distro (or boot from live medium) and test sound
    - install clean windows, retain generic hd audio controller driver and test sound

    If this bare system works ok, you can one-by-one add hardware & install device-specific drivers and software; test the sound quality after each step.

    I suggested that, except for Linux and that won't fix a windows problem, early on and he claims he's done that.

    So I've done everything everyone has recommended and nothing has changed, can anyone read one of my reports to show me what it is?

    Appreciate your frustration - have you tried pm'ing user Zinou as I suggested way back- zinou is familiar with these reports.

    And what happened when you tried a live boot disk? - I mentioned Kyhi's - which is now harder to download. People have had some success using Free Download Manager.

    After a month or more, and trying everyone's recommendations and having zinou help me out with many painful traces and long waits, (As suggested) we couldn't come to any sort of solution.

    So I bought a new motherboard, upgrading from a z370 to a z390 chipset board has gotten rid of all latency (that I can hear anyway)

    Also my old mobo was 90 pounds, my new one is 270, so a big upgrade. anyway, case closed now!

    I'm new to this forum but have had the same problem with my year old Dell Inspiron laptop. I'm obviously far less knowledgeable than most of the posters here - I'm simply sharing this because hopefully this can help people who have had the same issue.

    This has been an absolutely nightmare to troubleshoot, as scouring the internet there (1) appears to be a number of different causes for these latency issues involving storport.sys and (2) a number of the solutions seem so impressively random. I saw one person resolve this by rolling back the Intel RST driver, another by taking their PC outside and blowing some dust out, and another that seemed to fix things by simply going into (and not changing anything) in the BIOS.

    For me, the latency issues also appeared frustratingly random. Out of nowhere, the computer would be almost unusable, I would try a million different things, and then 'voila!' something I did seemed to solve it.

    After about seven months of painful trial and error, I think I've stumbled on an answer. The biggest hint was when I took my laptop to the Dell Service Center after a week of paralyzing latency, and of course because of Murphy's law it magically worked fine when I opened up the computer and the service rep took a look. This is what I've found works, for me at least. It's easy enough that I'd say it's worth a shot for anyone else struggling with this:

    1. Fully shut down the computer, plugged in
    2. Unplug the computer. Wait ~30 minutes
    3. Plug the computer back in and turn it on.

    Why this works, I have no clue. But it's worked twice for my machine when the DPC latency issues have started to resurface, and also helped a friend of mine who also has a Dell laptop that was having the same problems.

    I doubt it's a universal solution, but for anyone reading this it might be something to try.
