I am discovering that there are problems using headsets with on line games.

It's not really an issue for LAN games that are in just one building,
but could be useful if say your neighbor(s) is/are playing from their home.

So Vista will recognize my "plug" headset is plugged in but won't get sound from the mike.

I did a search and found out that a number of people are having the same or similar problem
(some can't get sound from the headset). Still looking for a solution.
