do other usb devices work......it could be that the when you built the system you hooked up the connections to the usb headers wrong.........
Yes every other usb port works fine no matter what I put in it except the speakers. The speakers defiantly work because they light up once I plug them in. Windows just does not recognise them at all. I just really hope its not a hardware issue.
Could it be something to do with my graphics card ? which is a 6850 when I go into control panel to check the speakers its showing that I am connected to HDMI realteck audio, it does not give me an option to switch to speakers its grayed out.
