Creative SBS A500 5:1 Speaker not working

Hello,

My creative 5:1 speaker is not working. What should I do ?

I'm using core i7 6th gen & motherboard Gigabyte H110M-S2PH.

Also i don't have any external sound card.

Though I had used this without sound card in past year of 2009-2013 .

Please help me out with this as soon as possible

Thank You
