When I start up the Xulu system, I see a message saying: “VoiceComm Client Error” “could not open capture device”. After I click OK, the system starts up. What does this mean?

This error message is generated when the voice communications sub-system attempts to access your computer’s microphone but no microphone is found. This will occur if your computer does not have a microphone or your microphone is in the disabled state. In this situation, the system will still run OK, but you will not be able to communicate with other users via voice.
