I'm just wondering if anyone else has experienced this.
I have a Sony DA777ES home theater amp, a Power Mac G4 (dual 867, MDD), and a 15GB iPod.
If I connect the line out (either rear or front headphone) connector to my stereo, or the line out from the iPod dock, I get excessive interference. It's quite noticeable between tracks. I have noticed however that if I disconnect the FireWire connector from the iPod dock, the interference goes away.
