Yep, the other guys are correct. The headphone output has a dual purpose. It is also a mini-Toslink optical connector. Get a mini-Toslink to Toslink optical cable or a mini-Toslink to Toslink adapter plus and a sepaerate Toslink cable.
You might want to verify the above, but I'm 90% certain the headphone output is a dual purpose type.
