    my DPC lateny is still high and causing problems like interruptions during internet audio playback.

    Does anyone know a solution for this?

    kind regards

    Choppy internet audio is due to saturation of the internet. Turn off other downloads and P2P programs.

    only the drivers that could cause the latency and the buzzing were updated.

    could a driver fix the buzzing?

    Hi,

    make a xperf trace or Run LatencyMon [1] to diagnostic the DPC issues. Please upload the xperf etl file to your SkyDrive [2] and post a link here if LatencyMon doesn't help you to find the causing driver.


    Attention, please use the Windows 8.1 SDK [3] to get the WPT.

    I'll take a look at it.

    hello André, which commands should be given for the xperf?

    latencymon tells that the drop-outs are caused by lot of drivers. network, bios and even power management.

    what's WPT? surley not world poker tournemant

    thanks

    André,

    The buzzing and the high dcp's are related.

    zip the file to reduce the size. Post a link without HTTP or replace HTTP wit HXXP until your account is verified.

    The manufacturer suggested a complete formatation, but that did not change anything about the buzzing and the interruptions.

    The solution could be a complete new computer with different hardware.

    you have some USB isues:

    Total = 427492 for module USBPORT.SYS
Elapsed Time, >      256 usecs AND <=      512 usecs,      1, or   0.00%
Elapsed Time, >      512 usecs AND <=     1024 usecs,      2, or   0.00%
Total,                                                427492

    Play a bit with your connected USB devices (Wacom, Logitech, camera, USB card reader) and look what happens if you disable one of them.

    Hello,

    It is not the use of internet that is the problem.

    It is by me a driver problem, but now with a different network card and disabling the centrino intel card the audio is more persistent.

    Thank you.

    kind regards, Wouter
