Problem with soundcard

Hello! This is my last hope…asked everywhere but with no result. So, I bought myself a new pc, this is the motherboard: http://www.gigabyte.us/products/product-page.aspx?pid=5123#ov and i want to use it with my Echo Layla 3g. The OS is windows 8.
So since i don’t have an pci-x port on my mobo, i use this http://www.ebay.com/itm/201177854714?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT.
There is no problems with the drivers…all it’s ok…
So…the final thing is that the output is a very big distortion…

What can i do? The echo team won’t respond…so…

Many thanks in advance!
