So I am plugging my speakers directly into my motherboard but when I try to play music through them all of speakers work apart from the sub woofer. I have tried testing the speakers through windows and when I do so the sub woofer works. I'm so confused.
These are the speakers: http://www.amazon.co.uk/gp/product/B00AGSSMJM?keywords=gx%20speakers&qid=1450447974&ref_=sr_1_4&sr=8-4
This is the motherboard: http://www.gigabyte.com/products/product-page.aspx?pid=4959&kw=GA-Z97X-Gaming%2071.0#ov
