SYMPTOMS
You use a USB-enabled handset or a USB-enabled headset to connect to a Microsoft Windows XP Professional Service Pack 2 (SP2)-based computer for VoIP communications. When you try to use the &quot;Set Up Audio and Video&quot; wizard in Microsoft Office Communicator 2007 to adjust the volume of the speaker or the volume of the microphone, the speaker control test or the microphone control test is disabled. The slider controls for the volume of the speaker and for the volume of the microphone may be disabled. Additionally, the controls may be set to a predetermined setting.



CAUSE
This issue occurs because Windows XP Professional SP2 sets the audio device's speaker and microphone to the predefined default volume settings.



STATUS
This behavior is by design.
