Thanks for the reply. That's a bit annoying, i'm surprised I haven't heard anybody else complaining about it. Does anyone know what the problem is? I can see two solutions, some sort of hardware fix, or software that keeps the line open? I don't know whether such software would effect power consumption, but if it just kept the line "open" (it only makes the noise when it starts, it's fine when it's going) I think that might solve the problem.
