Need some help, HD Audio Cable into Intel HD socket? Pictures inside.

Finishing up a build for my son. The mobo is an Lenovo Ih81m. Yes, older, but my 4th gen i7,4875T works with it. I’m finishing everything up (had to make a 24 pin to 14 pin psu cable), but everything else seems fine. However, I cannot figure out what to do with the HD audio cable from the case. The motherboard, from my research (see photos), uses an Intel HD socket, labeled “F-Audio.” Not sure how to connect my HD audio cable to it. Pins don’t align, etc. Please help me
