Hey guys, Yesterday I was trying to fix my Logitech's speaker system while it was connected to my MBPr 15". I know, I'm an idiot. I was playing with the system's cables to find out which was the stereo audio ones and suddenly the right audio channel of the Macbook's headphone jack stopped working, it now has only a noise that keeps changing intensity. The left channel still works fine. As screwing up my laptop wasn't enough, I tried to test the speakers with my iPhone (thinking the problem was in the speaker's cables) and boom, same thing happened. Now I have two devices with only one-channel audio output. I'm feeling the dumbest person in this world to have accomplished that. Anyway, I wonder if replacing the mac's headphone jack and the iPhone's dock would solve this issue, or if the logic board might have been damaged as well (my worst nightmare). Help me, please!
