Whenever I skype with someone, they can not only hear me, but my computer sounds and my music clearly as if they are playing it themselves. I have headphones that have a mic built into it and I was wondering if that would be the problem? Oh and I also can not access any settings such as audio through skype, only through my mac book. Please help, this is getting very fustrating. That picture is what my skype looks like, and as you can see, there is no where to click any settings and such.
I'm not sure why your computer sounds are being transmitted, unless whatever mic you are using is picking up the ambient sound. That aside, the sound settings are to be found in Skype's Preferences (they're a dropdown menu under Skype at the top left end of your menu bar--next to the Apple icon).
I had the exact same problem discovered today...after 40min of my life and no real clear answer, I have discovered this: even though the recording devices under the sound control panel are disabled, they are not fully 'disabled.' What I ended up doing is re-enabling the stereo mix and realtek digital input (do the same for the equivilent on your computer) and turned the levels (its own tab) all the way down to 0. Worked for me.

If you go into your skype settings (Where you chose which mic to use and such) turn them all down. If you are on windows turn down or disable stero mix. This should fix the problem if it dosnt factory reset your computer or manualy update skype. Mabey updating skype will work if all else fails.
