lol im back with a nother problem...well i jst got a ne mic and had not used it on my pc as it was out o action but it worked fin on my laptop and my bros but now when i try use it on my pc i get none or little sound comin through but fine sound in the speakers...do you think i should reinstall my sound card to or is there another thing that could be bugering it up? (all sound options are on max and i have tride front and back ports even though i think the back one is broke...)

Increase the master volume on the line in. Goto start/contol panel/sounds and audio devices/volume/device volume/advanced/on the master volume make sure the line in slider is at max and the mute box is unticked.

nope they where alredy set as how you said to...i have retested the headset in my laptop and it does work fine...grrrr

Try updating the driver for the sound card. GOTO start/control panel/sytem/on the hardware tab select device manager.in the list find "sound,video and game contollers, click on the box and a further tree showing installed devices will appear, you can right click these and an option to update drivers will appear. Do this for all audio devices. See if this helps. If not try a reinstall. If that doesnt work, it could be as you say a broken connector, could you borrow another soundcard?
Another option is to visit the windows update site, you can let Microsoft scan your pc for any updates. You will then be presented with a list of updates. On this list see if any are related to audio options, if they are download and instal.
