Hum/static on external speakers with Powerbook

[vgoklani]

Hi,

I have a powerbook G4 (aluminum) and I recently attached a pair of external speakers to it. I have noticed a faint hum, which I find to be annoying. I set the volume on the PB to 5/8's max, but it's still noticable. My speakers are fairly high quality, and I don't have any problems when using it with my PC (attached to a M-Audio Delta 410). On the PB, they are coming out from the headphone output. I wish Apple made a Line out on the PB, but they didn't. Are any of you guys experiencing the same problem? any solutions?

something is causing interference. You need to move your speakers from electronic devices. for example, my speakers are fine near my CRT, but right up against the CRT it causes the noises. Also, placing radio device near the speakers will cause problems also. radio device can be anything for cordless phones, cell phones, and radio/tv. changing the source of power to the amp. you might be hearing the buzz from a flouresent light on the circut.
