Headset not working properly

[Guest]

I have an e machines T-1120 PC with Windows XP service pack 2.
Today I purchased a LogiTechChat headset. I plugged the coonectors in the
rear and though I can hear perfectly, no one can hear me.

I have done the following:

1. ensured all connections are correct .
2.ensured headset mic is not muted
3. I also made sure that the volumes on Start/Control Panel/Sounds and
Devices/Volume and Advanced are not muted and at least halfway up
4. Tested the Sound Recorder, and it will not record any voice from the
microphone
5. Ive called Logitech's help center and they say since the microphone is
working (ive tested it on another computer), then they assume it is either a
sound card issue or a driver issue, but won't provide assistance
6. E machines support says this is an accessory which did not come with the
computer so they can't help.

In the Audio mixer, do you have the Microphone "Selected" for the
recording mode (Not Playback). Also, many headsets have a switch
in line for muting the microphone manually.

"In the Audio mixer, do you have the Microphone "Selected" for the

check mark in the box to make it muted.
