I have the 5.1 Home Audio speakers hooked up to my home computer. Earlier today, they were working fine. Then they all of a sudden stopped working. Theres now an audible constant popping noise out of each speaker EXCEPT the sub, which sounds muddled. I took all the wires out testing the connections and I noticed the popping stopped, of course. I have an Audigy EXGamer hooked up in the furthest slot on my mobo. Ive tried reseating the card, turning the comp off and rebooting, unhooking all wiring and re-wiring but to no avail. Any ideas?
