For some reason there is a continuous buzzing noise from me over any kind of communication (I don't know what to call them, but for example; Skype, TeamSpeak, Mumble, in-game chat). When people first started telling me about the buzzing, I thought it might be my headset (SteelSeries Siberia V2), but the buzzing didn't go away when I muted the mic or even unplugged it. Now I'm worried that it's my "sound card." I put that in quotes because I'm using onboard audio (RealTek HD Audio). The buzzing is just a static-buzzing type of noise, the kind you will always hear in one game lobby or another. If anyone could help I'd really appreciate it! Thanks!
