Hi, my problem is that my microphone is plugged in, everything is enabled, sound turned up to its max, mute button is not on, and STILL no one can hear me in-game! When I hold down the push to talk key, the little icon shows up but my voice does not. I run this game on max graphics, high sound quality, and there is NO lag problems. I have windows vista home premium ( I heard this is the best for gaming). But get this, when I run a test via Control Panel, everything checks out a-ok. When I run a test within the setting of CS:S the voice bar doesn't move a bit. When I go into the steam community settings all it does is make a wierd brrrrrrrrrrrrrrrrrrd...... sound. Should I stay with Vista or put XP back on? Could it be my headset? (always worked before, if it is, please provide a link with a gaming headset no more then $50.00)
