  2. Update Your Computer's USB 3 Chipset Driver

    If using Windows 7, make sure to update your motherboard's USB 3 chipset driver by following the directions in this article

  3. Disable Core Parking & CPU Throttling

    Intel processors feature CPU power management abilities that dynamically change clock speeds and sleep states. These changes can adversely affect real-time audio. If you are experiencing pops, clicks, or beeps then we recommend that you disable these features.
     
    Most systems will allow you to turn off or adjust these CPU power management features in the BIOS / UEFI. Please consult your motherboard or system manual for help with making any changes in your BIOS / UEFI.
     
    By disabling the following features your system will run at a constant clock speed and will not halt individual cores, which can result in better audio performance:

    • Intel SpeedStep (or EIST)

    • Intel Turbo Boost (or Turbo Mode)

    • C-State Control (or C1E, C3, C6, C7)

  4. Enable USB Safeguard

    Enabling USB Safeguard in Console can help alleviate issues with audio playback. For details, see this article.
