input level auto adjusting

[bitdotpixel]

Hey,

My sisters mac book pro has been auto adjsuting the input level even when we manually set it. The result is severe output for whoever we are audio-chatting with. Its actually cracking speakers. I've never had this problem on my other apples. However, it's our first laptop...is this a common laptop feature? Can I disengage? Perhaps in terminal?

Thanks,
John

Is this with the internal microphone or with an external? Does it get reset to the maximum or to the centre?
