Hi all, Recently bought a Dual 2.0 Power Mac and am very happy with it except for the speakers buzz interference and ticking noise. The question I am asking is would the "M-Audio Revolution 5.1 PCI Audio Card" fix the problem or would a set of speakers with digital input clear the problem instead. Does the digital output bypass the sound interference? If so, then can anyone recommend a good set of 2.1 digital speakers that are available in the UK? Thanks for any help. At the moment Im just using the internal speaker as its driving me nuts using the speakers at the moment. Glyn.
