I have just unplugged the three cables from my onboard sound and ......The buzzing has gone so i take it, it's the onboard sound causing this proplem, I have just tried my old creative soundblaster live 5.1 soundcard and it works fine with no noise so ill have to stick this in for the time being, whats a good soundcard to get when i have some money????? prefrebly 7.1 even though im using 5.1 lol and HD like my noisy onboard one lol???
