I got a problem when it comes to my headset on my gaming computer. It works fine on my other computer when it comes to games but when I plug it into my other computer it works still, but when I go into any Steam game I have the microphone of the headset doesn't want to work at all. I asked Steam this about a week ago and they still haven't responded with an answer yet. And now, my speakers on the same computer with the microphone problem forget up Left4Dead 1 sounds. It kind of gives it a "Wah wah" sound. I don't know why, it hasn't done this in any other Steam games, but only Left4Dead. My speakers are the X-540 5.1 Speaker System by Logitech.
In short: Microphone works but somehow won't work in-game, my speakers are loving up Left4Dead 1's sound, and Valve is still sitting around with their thumb up their fat sweaty asses.
Think anybody has an idea of what my problem is?
