Hope This helped!
Good luck!

First go the system preferences and then sound and then click on the input and ensure that the built-in microphone is selected and check the volume is set to whatever you need.

In google chat go to options and then down to chat settings. You can then go to microphone under Voice and video chat and under microphone select either default device or built-in microphone. You can then verify your settings.

Hope this helps.

You may need to go into your audio settings and select the correct microphone.

just down the mic volume and see als run the sound diagone test.

Troubleshooting - Can't get voice chat to work.
Here are a few things you should know and check for to get the voice chat to work. · Firewalls - the voice chat feature may not work well behind company firewalls. Even though you can get other features of Yahoo! Messenger to work, the voice chat feature uses separate technology and may not work as well.
· Check connection - When you enter into a voice chat with friends, each participant should take turns trying to press and hold down the Press to Talk button. Everyone else should see their name turn red when they do that. If you see their names turn red, but don't hear anything, it may be a microphone / speaker problem, or it may be that we have more bugs that we need to fix. If you don't see their name turn red, you are probably having connection problems and that's why it's not working.
· Get the latest version - Please make sure that everyone who is using the voice chat feature has the latest version.
· Check mic and speakers - Check that your microphone works and that your speakers are turned on. Here's how:
* make sure the mic is plugged in correctly.
* adjust the mic properties.
- go to the control panel (start button -- settings -- control panel)
- click on the multimedia icon
- you should see a tab for audio
- make sure that the recording volume is set high.
* you can test your mic. by doing the following.
- Click the Windows Start button, then go to Programs, then Accessories, then Multimedia, then click on Sound Recorder
- A new window called Sound Recorder will pop up. Click on the record button (a red circle), then say a few words, then click the stop button (black square).
- Click the play button (black triangle).
If you can hear yourself fine, then your microphone is okay. If you can't hear your voice using Sound Recorder, the voice chat should not work either.
