A while back my USB mic bust up. Recently I got it replaced and it works perfectly, brilliant sound and great for using for convos on Skype/Teamspeak etc. However in CSS, no one can hear me. I've played on loads of servers, and when I press the button the little speaker icon comes up, but no one can hear me. However in options when I test the mic I can hear myself. Strange... any help? Thanks ever so.
