The audio device on a Windows Vista-based computer does not work after you use the Windows-based Live Meeting 2007 client to join a conference

The audio device does not work on a Windows Vista-based computer after you use the Windows-based Microsoft Office Live Meeting 2007 client to join a conference,.

This issue occurs when there is a conflict between Windows Speech Recognition in Windows Vista and the Live Meeting 2007 client. When Windows Vista starts, Windows Speech Recognition also starts. Therefore, the Live Meeting 2007 client cannot use the audio device.

To resolve this issue, make sure that no application has exclusive control of the audio device. To do this, follow these steps:

1. Click Start, click Control Panel, and then double-click Sound.
2. In the Sound dialog box, click the Playback tab, click the speaker device, and then click Properties.
3. Click the Advanced tab, click to clear the Allow applications to take exclusive control of this device check box, and then click OK.
4. In the Sound dialog box, click the Recording tab, click the microphone device, and then click Properties.
5. Click the Advanced tab, click to clear the Allow applications to take exclusive control of this device check box, and then click OK.
