Hello all, I have had this problem since I got my Macbook in 2010. When I am on Skype, or anything that uses the internal microphone, all sounds generated from the computer itself are extremely loud. For example, if I am talking with a friend on Skype and I open a Youtube video, the sound from the video will be unbelievably loud for my friend. Everyone says it hurts their ears how loud these internal sounds come through on the other side. Is there any way to reduce this? I know that obviously the microphone will pick them up anyway, but is there something I can do just to tone it down? Thanks in advance. If I was unclear or you have any questions, please ask so that I can clarify.
