However, they can match physically. For instance, the position of the pins and the 1 empty space match.
If these pin assignments don't match, can i just not plug them? it's just audio right? I could just use speakers?
Yeah, its just for the front audio ports on your case so no biggie. Just don't plug them in or if they don't match then work it out yourself as it is pretty straight forward. The only one I think is really needed is the speaker connection so that you get the system beeps to help you troubleshoot in times of crisis but even that is not a necessity.
