Audio Theory, Setup, and Chat > Motherboard 3.5mm analog sound to either digital coax or toslink?

Can anyone help me solve this:
I have an HTPC I just built and I have this motherboard: http://www.biostar-usa.com/app/en-us/mb/introduction.php?S_ID=615

From the motherboard, I would like to have the sound come out and go into my Sony soundbar: http://store.sony.com/p/HT-CT150/en/p/HTCT150

I have an open Toslink and an open Digital coax. I can't use HDMI sound because I have my PS3 screwing up using the soundbar as a monitor.

So long story short I have 6 analog outs on the motherboard and 1 digital coax or 1 toslink port available. Any suggestions?

A USB audio interface like the one below would give you an optical output to connect to the sound bar.

Thanks, if I have to go that route, I will probably just buy a PCI card with toslink or coax out. I was hoping to get by with a solution that didn't involve more money since I have a million different cables in my cable/hardware container at home.

Worst case scenario - 3.5mm to dual RCA analog connection

Doesn't the Biostar Hi-Fi A85W Ver. 5.x mb also have an internal S/PDIF-OUT Header on the board you could use?

As SoundChex suggested, there is and S/PDIF output on the motherboard (Toslink and digital-coax are both forms of S/PDIF). So it is simply a matter of getting the right cabling to directly connect the motherboard's S/PDIF output to the Sony's digital-coax.

Yes there is a SPDIF header on the board, but how do I utilize it? I am not sure how I hook a toslink up to that.

Thanks Mark, I ordered one. I appreciate it. I hadn't seen that part before, go figure.
