Hey all, I have a Quicksilver G4 which i've recently re-activated after a long hiatus, and it reminded me of its audio issue. When i plug in external speakers, it would hiss fairly badly irrespective of workload or what activities I'm doing on it. Since my G5 has failing HDDs (with little cash to replace), its looking like I might need to bring the G4 back into service. Otherwise it works flawlessly (aside from an odd graphical glitch in Leopard, runs brilliant in Tiger). Any help/suggestions would be greatly appreciated (not sure of its year, but its a Quicksilver 933mHz single G4 with 768mb RAM) EDIT: There is no hissing or anything from its internal speakers at all, only from the audio jack.
