My friend and I both have a logitech webcam.She can hear me, but I cannot hear her.We both did the mirco/speaker test.Whos end would the problem be on? Thankyou,Deb


Hi Deb,

It could be either one of you.

Make sure you both have the latest updates for the webcam and for the graphics card drivers in your computer.

Exit from any other program using the webcam. e.g. if you are using Skype to chat with your friend then Exit from the logitech camera software before starting the video call.

Click Start > Run and type dxdiag then press OK. You should have at least DirectX 9.0C.

Does this help?

Hi ihave an acer aspire 5600 .My webcam works with other aplications but not on skype and msn.Could you please help me?


Before you can use your webcam in any chat program you have to configure it to that program

Test your webcam here to make sure it broadcasts ok - Hit 'Allow' in the top window and check your cam in the left hand panel.

working OK ?

CONFIGURE TO SKYPE
Connect webcam
Its good practice to disconnect and re-connect your webcam before you start (To reboot the webcam software) - if you have been using it elsewhere the SKYPE software may have difficulty in locating it, even if you exited the previous program correctly.
The reason being, the webcam software can remain hooked-up to a program and needs to be rebooted.
Mine, I just unplug it from the USB and plug it back in to reboot the software.
If yours is integral with the computer you will have to re-start the computer, use a keyboard shortcut or disable / enable the webcam from the Device Manager.

Start Skype.
On the 'Tools' menu, click 'Options'.
In the navigation pane of the Skype 'Options' window, click 'Audio Settings'
Run down the list setting your defaults
Select your webcam as the default microphone.
Make a free test call
Click 'Save'
In the navigation pane of the Skype Options window, click Video Settings.
This will launch your webcam
Adjust quality of picture in 'Settings'
Check the correct webcam is shown as default
Click Save
Test your webcam by making a Skype test call.
For more information about how to configure Skype Messenger, please visit the following Skype Web site:

WINDOWS LIVE MESSENGER ( MSN)
Test your webcam here to make sure it broadcasts ok - Hit 'Allow' in the top window and check your cam in the left hand panel.

http://www.testmycam.com/

Having proved your cam is working ,you can configure it to WLM (MSN)

CONFIGURE SOFTWARE to MSN
Its good practice to disconnect and re-connect your webcam before you start - if you have been using it elsewhere the MSN software may have difficulty in locating it, even if you exited the previous program correctly.
The reason being, the webcam software can remain hooked-up to a program and needs to be rebooted.
Mine, I just unplug it from the USB and plug it back in to reboot the software.
If yours is integral with the computer you will have to re-start the computer, use a keyboard shortcut or disable / enable the webcam from the Device Manager.

Open MSN
Click 'Open Menu'
From 'Tools; navigate to, and click, 'Audio and Video setup'
Set your speakers
Click 'Test' - if OK, move on.
Set your mic as default
Use the slider to set volume and test.
Click 'Next'
This takes you to the video setup
Your webcam should be broadcasting - (if not - make sure the webcam is set as default - restart MSN)
Use 'Webcam Settings'to fine tune the picture.
Click 'Finish'

Go into the device manager, and make sure there are np problems. Start, settings, control panel, system, open device manager, locate the web cam and look at the bottom, make sure it is working, "it will tell you", make sure it has the most recent driver etc. exit out of everything and go to start programs again, choose your webcam program and see if it needs a firmware upgrade. it should show u when u look at the program, and if noothing seems wrong, then just re-install the webcam. peace, Gym

Got a solution... you have to close and exit the A4tech (AMCAP) screen. Then start the yahoo webcam by clicking the "My Webcam" on the yahoo messenger. At this time, you should be able to see yourself at yahoo webcam.

Normal 0 Did you install the software with the camera connected to the computer? Disconnect the camera from the USB port and reinstall the software. When the program asks you to connect the camera, do so, and it should work. Hope this is of some help. Bud

Below is info for setting up Audio & Video to chat on line after you install , either Skype or a messenger program.


Web Camera’s have to be setup on the program they are to be used with. Just installing the camera on your computer does not set it up to broadcast on messengers or Skype.
Each program has Options that have to be setup in order for the Audio and Video to function properly.
A. Skype Setup:
After downloading and installing Skype set it up as follows:
  1. Go to TOOLS, then OPTIONS, and click on Audio Settings and set the Microphone and Speakers to the computer Audio Card.
  2. Then click on the Video Settings.
  3. The camera if installed properly will come up and show a 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 see and talk to you.
B. Yahoo Setup:
After downloading and installing Yahoo Messenger set it up as follows:
  1. Go to Messenger at the top left and click on it.
  2. Next go down to Preferences and click on it.
  3. Next Calling and Devices on the right and set the Microphone and Speakers to the computer Audio Card.
  4. Next go to the Test Audio section and (in blue writing) click on “Open the call setup assistant” and follow the instructions on the left window.
When done both the Audio and Video will function properly so you can chat and see family or friends you are connected to.
Hope this helps. Bud

Exiting webcam applications


There might be some sort of background program running for the camera. In the bottom right of your screen, next to the time/date, right click and exit anything you're not using.
