I have a PowerMac G4 Dual 1.25 MDD that is just over a year old now, and I have strange noise and static coming through the sound card all the time. It's been there since I've had the machine, and when I asked Apple they insisted that it was my speakers. I decided to plug headphones directly into the speaker output and the static is still there.
Has anyone else had these problems?
I will have to call Apple again, but I have to find a time where I can go a few days without my mac.
Note: I tried to do a search on this topic, but MacNN's search engine has been down for a little while.
