    Hi,
    I'm getting audio drop outs when I use Native Instruments Komplete Audio 6 adio interface with my windowns 7 64 bit. This issue happenings during playback and recording. I have established that the issue is not related to komplete audio 6, but actaully windows 7, my intel chipset drivers or just my machine.

    When I run latency monitoring on my machine, I get the below stats back.
    The folowing drivers seem to be the problem.
    ataport.SYS
    tcpip.sys
    mfefirek.sys
    ndis.sys

    Can anyone help????

    CONCLUSION
    _________________________________________________________________________________________________________
    Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

    Also, I have already updated my drivers with teh latest available from Intel and Native Instruments.
    Any advice anyone? Here is the spec of my laptop. It should be well fit to handle real time audio.
    Manufacturer: Dell
    Model: XPS L702X
    Processor: Inter(R) Core(TM) i7-2860QM CPU @ 2.50GHZ
    RAM: 8GB
    System Type: 64-bit OPerating System
    Windows Edition: Windows 7 Ultimate

    Could it be the hard disk that's the bottleneck ? You don't mention the make or model of it. Might also be worth disabling any AV (mfefirek.sys is a McAfee AV firewall file) and checking Dells website for up to date drivers, don't rely on MS provided ones !

    Edit: Might also be worth checking your swapfile and if possible move it to another partition with a fixed size. If this file gets fragmented about the drive is could cause slowdown ?

    This is the hard drive:
    HARD DRIVE : 1TB (2X500GB) SERIAL ATA (7
    ST9500420AS ATA Device
    Where can I find my swap file?
    Also I'm struggling to find the mfefirek.sys to disable it. Its not in my device manager. Where can I locate this to disable it?
    This driver seems to be causing the most problems. ataport.SYS

    ataport.sys is I believe related to the hard disk or CDROM. Or at least the ATA system, which looks after the IDE devices in your computer. The Intel drivers are something like smartstor as far as I can remember. Try disablng your McAfee AV system and see if that helps would be my first action. One of the files you mention is related to the MacAfee firewall and AV service, if the AV was scanning everything that entered your hard disk then it might be slowing down access and have an impact on all of those services you listed.

    There are several posts found on Google that relate to latency issues all to do with the Intel SATA drivers but I suspect it might be McAfee that is causing your problem. Easy way to find out is by just disabling it. If it's in your System Tray (bottom tight hand side beside the Clock) then there could be an option to disable it ?

    When requiring low latency response it's important to disable anything else that accesses your hard disk as a starting point, especially when getting video from a camera or audio. AV software could potentially be scanning your drive at the same time you're trying to write to it, i.e. recording.

    Hi there - I disable the firewall but it didn't improve. Below are the results from LatencyMon
