in cs you have to go into the options and configure the mic and you should be able to test it before going into the game. Then assign "mic" or whatever it is to a button then go into the game and try it
yea I knew that, I tested it and the bar didn't rise
Bring up your Full sized volume control, select options -> properties then click recording and ok. Now make shur the selected source is your microphone.
Recording is grayed out
