Logitech Z506 black and yellow cables into ASROCK z170 Pro4s board that doesnt seem to have b/y jacks

[first time rig]

My motherboard asrock doesnt seem to have black and yellow cables audio jacks only blue, pink, and green so how can I use the logitech z506 5.1 black and yellow cables so that I have true 5.1? thanks.

I seems like your mother board doesn't support 5.1 surround sound. You might want to consider a sound card. If you are on a budget i would consider this startech card:

If you have a bit more cash here is an Asus card that people seem to really enjoy:

Now if you want a higher end card I would suggest at least a Creative Sound Blaster Z:

Those are some internal cards. Im really not sure what is better but here is an example of an external sound card:

I hope this helps at least a little bit.

This motherboard (mentioned in your title ( supports up to 7.1 audio channel. If it does not have it, then you have a different board. Can you make a photo and show? Where did you buy the board?
