Considerations for Using Audio and Video

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

Many audio and video issues are the result of missing or out-of-date drivers for audio and video devices. When doing troubleshooting, begin by taking the following steps on client computers:

  • Install the latest critical updates from Windows Update at https://go.microsoft.com/fwlink/?LinkId=83424.

  • Follow device manufacturer recommendations for installing the latest drivers for all system components and communications devices on the computer.

  • Follow the computer vendor’s or manufacturer’s instructions for installing the latest system BIOS for the computer’s motherboard.

  • Disable audio effects that are provided by third party device drivers and associated software.

  • Either keep USB audio and video devices on separate USB controllers, or if more than one USB audio or video device is used on the same USB host controller, disable the Automatic Bandwidth Management Filter. (In the computer's properties, on the Hardware tab, click Device Manager. Right-click the device, and then click Properties. On the Bandwidth tab, deselect Automatic Bandwidth Management Filter.)
