Try reinstalling the sound driver and also check the volume for the mic.

Make sure ur mic settings are configured properly.

Open Yahoo Messenger Window, goto Actions > Call Setup as seen below:
Now follow the step by step instructions, and select the input and output source from the drop down menu on the setup screen until the microphone and speakers are working properly with this wizard.





Yahoo Audio Prefernces
Go to yahoo messenger main window , Messenger > Preferences > Calling & Audio
In this setup, select the microphone input from the dropdown, and similarly the speaker settings.



After selecting the proper input and output, the voice char worked just fine with me. Hope it helps you solve your problem.

when i call other person cant hear

it could be the problem from other side... the microphone settings on the other person side is not configured properly...

also try this:

On your Yahoo messenger, after you logged in:

Click Messenger >> Preferences >> Calling and Devices >> In the Test audio click "Open the Call Setup Assistant" walk through the wizard and see if you can hear the sound in your headset.

right click on the username you want to call,choose call computer,make sure that you have a headset and mic attached to your computer and so the party that you are calling..

Yes you do indeed need to have Vista Drivers, That said sometimes the XP drivers MAY work if they and the software are installed in XP Compatibility Mode. Vista has been a nightmare for us in the Computer repair industry... one can only hope that all driver issues are addressed in any service packs to come? I doubt it tho...It seems a case of out with the old and in with the new...wheather ya like it or not.
