I know absolutely nothing about Audio. I know that my speaker set up has a subwoofer. That it connects to the back of my computer through a black, green and orange 3-way spliced cable. I know I took the computer apart to move it to a new case and that's when it started. I use the on board sound card to an ASUS A8N32 SLI board with the proper sound driver. The assistance feature for the less informed, like myself, says there's something wrong with my green cable. There doesn't seem to be any tears or weak connections. As for the problem itself. Sound is mildly distorted. There's severe bass tones? where there shouldn't be. Half of the sounds from 3d games like Oblivion, do not register.
