Headsets and Speakers w/Vista Ultimate 64

Is there a fix for getting my Logitech Premium Notebook Headset PN980445-0403 (goes behind the ear) to work with Ultimate? I need to be able to use it with my headset jack and a splitter with another headphone set. I also need to be able to use it with the splitter and some external speakers, preferably the Bose Monitors. The mic jack works with the Logitech headset (above).

I upgraded to Ultimate and suddenly these things do not work!

I need to be able to record through the mic with my headset on while someone else is listening through their headset or comfortably listening to speakers. (No external mixers, no subwoofers).

Thanks.

Wow thats quite an interesting setup. How is it that it doesnt work? Does the computer not sense anything plugged in? Or does it see it, but no audio?
Does the computer sees it, but the mic doesnt work?

You need to tell us HOW it doesnt work.

SO:
Are you using onboard audio (the one on your motherboard) or a sound card?
Try using each thing seperatly, such as jsut the speakers, and make sure that each thing works individually first.

Let us know.
