Crackling Coming Through Speakers

There is an odd crackling noise that comes out of my speakers (External Logitech Speakers) when I am accessing the internet on my Power Mac G5. This occurs only when data is being sent and received, and the noise increases in intensity based on the amount of data being transferred. I am using a Realtek wifi usb drive that is fairly close to the speaker port, and am wondering if shielding is the issue.

Any Ideas?

What does the end of the cable look like that goes into the computer?

Try moving the speaker cable or the WiFi adapter to the front port. Does the noise still occur?

The cable is a standard 90 degree angle speaker wire. Fairly thin, has a bit of isolation though. I'm at work, so I'll have to try moving the wifi chip later.

The audio cable may have good electrical isolation, but poor EM isolation. You could try adding a ferret bead to it or using a more robust cable.

I always had problems if I used a cable where the back of the connector could touch the metal of the G5.

These would pose a static problem due to the metal on the base of the connector making a connection.

These tend to work fine in my experience:

Hmm, that seems to be the source of the issue. I will have to try covering that somehow or buying another aux cable. Thanks!
