The TeamViewer software package allows you to perform web conferencing and other functions that require the use of a webcam and microphone. The system depends on a Voice over IP connection to establish the audio transmission. This process requires reliable hardware to function. If your software is failing to record audio, you will need to troubleshoot both the hardware and connection to find out why.
Most computers today come with a built-in microphone. If your system does not have this feature, you will need to use an external microphone. It is the microphone that picks up the sound for the audio transmission. Without a working microphone, TeamViewer will not record any sounds. You need to see if you have a working microphone on your computer and check the settings. You will find the microphone properties box under the "Sound" option on the Control Panel. Once you open the Sound option box, click on the "Recording" tab at the top. If you have a working microphone, you will see it listed. If so, double-click on "Microphone" and confirm that the properties box states the device is working. Click on the "Levels" tab to adjust the sensitivity on the microphone.
Testing the Microphone
Once you know the operating system recognizes a microphone, the next step is to test the device with the Windows Sound Recorder program. You access the Sound Recorder from the Start menu. Select "All Programs" and then the "Accessories" folder. Open the Sound Recorder and use it to record your own voice and then play it back. If you hear no playback or get an error, you know the microphone is not working. You will need to use an external device if the internal microphone is failing or replace the one you currently have plugged into the computer.
TeamViewer relies on a Voice over IP, or VoIP, connection to send the audio. VoIP transmits via the Internet much like an Internet phone. With TeamViewer, you must establish a connection with someone and then start the audio. This is a separate step. The basic connection is a chat window. From the chat, you turn on the VoIP transmission. TeamViewer supplies a widget to manage this feature. To begin the transmission, click on the "Audio/Video /Voice over IP" option on the menu. When the widget opens, click on "Transmit my Audio Now."
If you know your microphone is working and the VoIP connection is on, but still cannot get audio transmission, turn up the microphone settings directly on TeamViewer. On the right-hand corner of the VoIP widget is a series of stacked lines. This is the icon for the audio settings. Once you click on the settings, you have the option to increase the sensitivity of the microphone. Remind the person hearing your transmission to turn up his audio settings as well.
