You may have to pick one that is GoPro specific or atleast GoPro compatible. Unsure why that one wouldn't, it's basically two contacts for mono or three for stereo, don't know why yours has four. Might be the adapter also. As I am a senior member of the broke homies club, here is the one I just got for my Hero2: http://www.ebay.com/itm/131533842925?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT
It works just fine and came with the skeleton case so I didn't have to drill. And the price was right for my budget. One note: make sure you are pushing in the plug firmly.
