Hello, I have two problems with my mbp and been looking around the forum and google without any clear answers. 1. When I'm video chatting through skype, even though my audio level is very low, the person on the other end can clearly hear whatever music/video I'm listening to. The volume on my mbp is at the lowest setting before being mute and the person on the other end can hear everything I'm listening to clearly when they should not. I'm assuming there's some sort of line-in problem. 2. There is this sort of echoing in skype. I can't explain the noise but it's like this echo/ringing noise that gets progressively louder and will go away once someone talks but returns when no one is speaking. I feel these problems may be related somehow. Does anyone have any idea what's wrong? I'm hoping this is a software problem and not a hardware problem. If it helps my mbp is the late 2009 model. Thanks beforehand.
