What is the name of that audio cable that goes from motherboard to case?

I realized that the audio jack connectors in front of my case don’t work.

After opening the case, it’s obvious, there is no cable connected.

The motherboard is a Gigabyte Z87P-D3 and the case a Fractal Design R2.

I’d like to buy that cable but I couldn’t figure out its name.
