How to connect PC to DVD player 5.1 sound? (no need video)


Aug 22, 2016
I googleing for a while and I just don't understand how to do this.

So, I have motherboard (B85M-HD3 R4) with intern 8-channel sound card (3 back and 2 front panel analog outputs) and I want to hook up 5.1 system on it.

BUT, I do not have 5.1 surround speakers. I have only one stereo (woofer + 2 side) plus one more woofer and 2 side without stereo (wooder is mono output).

SO, I have 4 side small speakers and 2 woofers.

And this is DVD player I want to buy

I know how to hook up speakers to DVD player, but I do not know how to hook up DVD player with PC??
I need this:
PC ----------> DVD player ---------> Speakers

And yes, I have GT 520 video card.

Is there any way for me to make 5.1 surround? Thanks!
