    Looks stable for me...just some little picks in the CPU, that can be latency or throttling maybe...I suggest you to watch out the time SP1 comes around.
    Yes, my system is stable. I'm an avid overclocker and that is obviously something I take very seriously. Before any one asks about the overclocking, yes I have set my BIOS to default settings and the problem is the same. It isn't really affecting system performance (although I am sure it would make a difference when running a stressful benchmark with audio playing via USB), it just should not be happening. It is NOT normal, nor is it latency or throttling.

    For example, when I use my video cards HDMI for audio out to my TV and watch a movie, my CPU never goes over 3-5% on any core.

    This is strictly a USB audio problem, and Microsoft knows about. Only when I use a USB audio device AND I am actually playing audio or recording, do I get CPU usage spikes.

    I will install SP1 on Tuesday when its released. I have hope, but I am not getting my hopes high. I am assuming the hotfix that I have installed will probably be the same version in SP1. I hope I'm wrong tho!
    Since you already applyed the hotfix, it might not fix this particular issue you're encountering. Let's hope MS provide another fix as they know it.

    SP1 is in two days!!

    PS: When i play music with my USB external soundcard, cpu goes around 5% to 21% and mostly 15%...i don't feel heavy cpu load...i've applyed the hotfix aswell.

    ... a USB 2.0 EHCI host controller

    Can anyone help? I am at my wits end with this.
    Hi,
    I have the same problem, when using my USB audio interface ESI UGM96 I get CPU spikes on one of the CPU cores. Doesn't influence the performance of the system but it's there and it's abnormal.
    Did you find a solution?

    Never did... I literally tried everything to try.
