Troubleshooting Audio Issues with NVIDIA graphics cards
Text size [-] [+]


For users with NVIDIA graphics cards, see these troubleshooting suggestions to try and resolve audio issues such as pops, clicks, dropouts, or distortion.
  • For users that do not play games, it is recommended to uninstall PhysX. Go to the Windows Control Panel and open Add/Remove Programs (Windows XP) or Programs and Features (Vista/Win7), select PhysX, and Uninstall. For users that do play games and require this component, disable PhysX from the NVIDIA control panel when using audio applications.
  • When using an upgraded video card, disable the on-board graphics card, including HDMI ports, as they have their own audio driver that can cause conflicts. Open the Windows Device Manager; locate the on-board video card under “Display Adapters”, right-click on it and select “Disable”.
  • Use the Disable Desktop Composition feature to temporarily disable Aero while your audio application is running. To set this feature:
    • Right-Click on the application or shortcut to the application and select Properties
    • Choose the Compatibility tab
    • Under the Settings section, check the box to Disable desktop composition
    • Click Apply
    • Now, whenever you launch the application, Aero will be temporarily disabled while the application is running, but re-enabled after quitting.
  • As some of the latest driver releases have been found to be interfere with audio playback, try running a different driver version for your NVIDIA graphics card to see if performance and stability improves.
  • If you have a laptop with an NVIDIA graphics card, check to see if it features PowerMizer Technology. While this feature provides better battery life, it has been known to cause problems with audio playback and recording. There are 3rd party utilities available that you can use to disable this. Click here for more info.
