I am trying to using the Supermicro X8STE in my build. I'm using the Ranger R4-R as the case. As far as I can tell, there is no port on the motherboard that matches the case's HD Audio cable. It is 2 rows of 3 pins with one hole filled in. Am I missing the port? Is there an audio port that doesn't necessarily match the case's cable but one that I can convert for it to work?
