Alright, this has been driving me mad and has stumped me short of going and getting a new sound card... I havn't yet because I don't have the money for it. I've seen this posted on quite a few different forums and people have posted answers to it but most of those answers won't work for me. Toggling mic boost in and out of TF2 doesn't do anything, nor does adjusting the sound... I can't simply mute line in and such in the recording panel for the fact that it doesn't allow me to, it just says select. Also skype, teamspeak, ventrilo and such programs work with not static, any advice?
