You can connect your laptop using a USB/SPDIF converter.

Thanks for the help. So I can't just connect this?

Oh boy. Okay. I was hoping to now spend that kind of money. I'll see what I can find. 

Thank you!

What about HDMI to coax? That's another option. Thank you. 

And now I'm looking at this. Too many options!
