Windows 7: headphones/Speakers not working with microphone

Hi to all..

I have been bugged down by this problem. Whenever I plug in the microphone in the jack the speakers stop. Same is the case if I use headphones.

I can't figure out if the problem is with the sound card or the with any drivers or is it something else.



I have updated the sound driver.
Checked that all nothing is muted and the volume is full.

The headphone speakers and mic work well when used on another computer, so no problem with them.

The Control Panel>Hardware and Sound> Sound> Manage> Audio Devices shows speakers and headphones both as well as the microphone. But if headphones is selected again i get no sound. Microphone doesnt work in any case.

I am using Windows 7 Home Premium.
The sound driver is High Definition Audio Device and its version is 6.1.7600.16385.

It's really frustrating because I cant voice chat with friends.
Any help would be greatly appreciated.

Thanx in advance.

Hi and welcome


Just a heads up. duplicate, (and triplicate) posts are discouraged as it divides the help you may get and makes it more difficult to follow
