There are several reasons this might happen. Here are a couple common fixes:

1. Quit all other programs that might be using your camera. e.g iChat, other video IM software.

2. Restart the browser and/or the computer.

3. Check to ensure the camera drivers are correctly configured on your computer. In windows you can test this in your control panel. In OSX [Mac] you can test this with other camera software such as Photo Booth.

Make sure your microphone is on and recording. You can check this by right-clicking TokBox -> settings -> microphone settings and talking or clapping. If you see a green/red bar moving, your mic works and the problem is on the other person’s side – see next question! If not, you will need to contact your hardware manufacturer for a solution.

Check if the volume bar at the bottom of their screen is moving. If not, the person you are speaking with may need to connect their microphone (see question above). If it is moving and you cannot hear them, make sure your speakers/headphones are not muted and working correctly by playing music in any application (e.g. iTunes, WinAmp).

This is caused by the microphone picking up sound from your speakers. Put on some earphones and it will probably disappear. If you are using a headset, try turning the volume on your speakers down a little. We are working on making sure the echo goes away altogether.

There are a number of things that can cause this.
