OK i get this problem with noise from my speakers coming from DSL modem.If i unplug my modem,the noise goes away.I have a good surge protector which is where all my computer stuff plugged into,even modem.I have 5.1 creative speaker system,which also has a wired volume control,which has a bass increase knob,and a headphone jack.When i plug headphones into this jack,i hear a tapping noise on low volumes,if i unplug modem,it stops.Without plugging headphones into this jack,listening to speakers,i get slight buzz,on high volumes,i know it is modem,cause problem leaves when i unplug it.I tried ferrite chokes on power line of modem,does nothing,i think maybe it's because cheap the power supply on modem,has no ground,meaning one prong wider then other,or 3 pronged for ground,somehow getting to speakers making this noise i believe this maybe problem.Now i tried plugging headphones right into the soundcards headphone jack and no problems at all,but like use one on creative speakers,and also believe this noise could cause other issues,either in modem or computer.I want to keep modem plugged into this surge protector for reasons of having a surge protector.
