    LatencyMon high latency sound card clipping.

    Hello, I tried so many things, running out of idea. Hope someone can assist.

    Updated all drivers, realtek, nvidia, amd chipset and bios. Remove everything from USB post and booted without services, disabled network drivers.

    When I uninstall the nvidia drivers I dont get that much latency, I do a clean install and using different drivers and it always comes back. I read on this thread that its some interfering with the drivers.

    My irq's seem strange the Microsoft acpi compliant system has 511 entry's is the normal?

    Did it change with later drivers now, or is it still the same, especially Realtek / NVIDIA ? Tried an older Flash Player Version like 11.6 or the latest Beta ?

    Try a different NVIDIA-Driver-Branch (the first 3 numbers of the driver version).

    Windows 32 or 64bit ?

    I have a recording studio (Sonar X3). I have an MAudio Fastrack Ultra 8R and do not have any sound or latency problems. I have the latest drivers, from Avid. required for Windows 8.1. I also have a Roland Octa-Capture with Win 8.1 drivers and no problems.

    I notice, in the screenshot list there is a "High Definition Audio Controller listed. That is usually a Windows installed generic, basic function, sound driver. If you have the correct sound drivers, you should not have the High Definition Audio Controller.

    What sound is actually clipping? The MAudio or the RealTek?
