using headphone/mic with compaq EVO D510 sff

[samidxb009]

I got desktop Compaq EVO D510 SFF with built in amplified speaker which works fine.
when i do voice chat using Headphone/mic, sound comes from built in speaker.. i tried many thing to disable built in speaker.. as of after plugging Headphone/Mic to its jack built in speaker should get automatic disable.. but in my case its not.. sound comes from both headphone and mic..
Can anybody help me to solve my problem
thanks

So the settings inside your audio manager are correct for app.?
If it is a RealTek go to the Upper Rt. Hand corner
[Device Advanced Settings] And click, 'mute speakers when headphone connected'
If other see if you may be able to find such a setting

Thanks for you reply Laska, I'll try your said option, but somehow i am able to start using headphone after removing and reinstalling sound drivers.
