I was cleaning off my desk today and rerouting cables. I spaced out for a second, and next thing i knew, the cord for my speakers (mini jack, not Optical) had brushed up against the airport antenna jack. The speakers let out a loud buzz. It was only in contact with the plug for about 1.2 seconds. Is there any possibility that I could have damaged any components? (Also, I DO NOT have an airport card installed, so the jack was not connected to anything)
