2. Then click on the Video Settings.
3. The camera if Installed Properly will come up and show a video picture.
4. Then, on the bottom of the page click on Save.

The camera and audio should function properly. Your friends and Family will now be able to see and her to you.

to download the Camera Diagnostic Tool and run it to check out your camera and/or problem.

Be sure the camera is plugged into the USB port before running the program.

As you run the program, write down the info about the camera so you will know what model and who manufactured the camera you have
attached so you can get the proper software drivers for it.
Hope this helps. Bud

I think it is related camera lens problem means hardware problem.If it is in warranty you can go for a replacement.

Sir,
Here are some suggestions:

• Try unplugging the camera, uninstalling all of the software and drivers, then getting the latest from Creative and reinstalling everything.
• Try installing the camera on another PC to see if it works there.
• If you're connecting through a USB hub, disconnect it and plug the camera in to the PC's USB port.
• Check the Creative web site for known problems
• Send Creative (CHECK WITH YOUR MANUFACTURER)  tech support an email to see if they have any advice.

Thanks Good Luck
Appreciate to rate as "Fixya"

unistall the camera driver. and reinstallk it.. and always use the same usb port for web cam

Click the 'Devices' menu and you should see a tick next to the Webcam name (USB 2.0 UVC Camera).

Underneath this should be the same name (USB 2.0 UVC Camera), select it and a tick will appear next to it.

This means that you are using the webcam as the mic for your video/webcam (instead of a seperate microphone).


Now click on the 'Capture' menu and the option 'Capture audio' will be available (previously it was greyed out)

Tick this/select it and your webcam will pick up the audio.

I hope this helps.

Also, if anyone finds the image a bit blurry, it can be sharpened bv rotating the webam lens.
