My computer doesn't have headphone jacks for my new headset. Can I buy an adapter?

So I just bought a headset, using 2 3.5mm jacks, and I come to find out, I don't have 3.5mm ports on my PC. Can I buy an adapter like this:

Actually it's my friend's, I just typed out what he told me.

He has an alienware i3 steambox.

that is the sound output on it Audio 7.1 optical audio out (Toslink) so no way to have headphones or you will need something like this https://www.amazon.ca/Digital-Converter-Optical-Toslink-Headphone/dp/B009AGTC3Q
