Lync or Skype for Business experiences warning about poor audio quality, lost incoming or outgoing audio, or generated echo in Windows 7

Gäller för: Skype for BusinessSkype for Business 2015Skype for Business 2016


When you use a USB device headset or speaker together with the Skype for Business 2016 client, the Skype for Business 2015 client, or the Lync 2010 client for an audio call on Windows 7, you experience the following issues:

  • Some incoming and outgoing audio is lost.
  • You receive the following error message:
    Your device is causing poor audio quality.
    Poor audio quality in Skype for Business
  • Other endpoints in the call hear a generated echo on a Windows 7-based computer.


Typically, only new hardware that uses a USB 3.0 interface is affected by this issue. This issue occurs because Windows 7 doesn't provide native USB 3.0 driver support. Intel provides the USB 3.0 driver stack. This causes timing issues in combination with the Skype for Business audio drivers.
