So I'm borrowing a mic off one of my friends (his way of trying to kick the WoW habit) and finally I have it working on CS. The problem is that now when I take the mic and headphone plugs out, my laptop makes an extremely loud screeching sound out of the speakers. I haven't tried changing the sound settings back to what I had before the mic yet, and that may very well be the problem.
Has anyone ever had this happen?
It scared the shit out of me the first time it happened. I thought the HD was dieing or something. Good thing this is only Bootcamp on my Mac, so if anything I'll just start playing CS on my old radeon 9800-equipped PC again.
