Hi folks. Just after some advice, I have a 5.1 speaker system for my pc and a 5.1 sound card. In the last few days my speakers have gone tits up. Only one plug on my sound card seems to work. I have 3 connections from my speakers...front, rear & centre/sub....they all work individually when i plug into the same hole on my sound card but not in any other hole....so i know my speakers all work fine. Plus when i try to connect to the other slots on the sound card there is a buzzing noise so it would appear they are working also. And i have checked that my sound setings on my pc are selected to 5.1. I am at a loss....it looks as though the sound card has packed in. So for the time being i can only choose to listen to my speakers via the front, rear or centre/bass only!!!! Any advice? Or is it a case of purchasing a new sound card?
