Stereo line noise is annoying

[Necrofire]

I get intermittenet beeps coming from my speakers. Googling the problem led me to believe it was interference from my phone. My phone is the cause of most of the interference, for it happens more often and louder the closer the phone is to my volume knob to my speakers. Sometimes the beeping is VERY loud and my phone will be nowhere near my speakers.

I've had a couple of hypotheses, but I don't know enough about electricity/magnetism/radiation to properly diagnose the problem.

My 2.1 PC speaker setup goes like this.
power goes into the sub woofer, two cables comes out to a standalone volume knob with line out, headphones and mic. Two other cables go out to a speaker a piece. I also have another wire for mic going from the volume knob to my pc. All the wires go through a tiny hole in my desk, which is the same place ALL the other wires to my computer go, power cords, monitor, internet, etc.

I've heard of numerous causes from the amp picking up the phone signals and amplifying them to the ac power line picking up the signal and transmitting it into any of the wires in the speaker setup.

What is this very annoying intermittent beeping I keep hearing?

Do you use a 2.4ghz phone? If so that is the culprit. If you must have a cordless phone, get something that operates at a different frequency.

BOTH mobile phones AND cordless phones cause these types of problems.

Try these fixes:

1./ Move phones AWAY

2./ Make sure the lead from the PC to the speaker amp is as short as possible... and is not wrapped round power cables. Keep as large a distance as possible between the audio out from the PC and any power cables. Buy a shorter one if there is oodles of spare cable. If you "wrap the cable" to shorten it... just dont LOOP it. Use your fingers and wrap the cable around them, not as a loop, but as a figure of 8. Use cable ties to hold.

3./ Get a graphite core and wrap your audio cable through the graphite core. (Look up if you dont know what this is)

4./ MUTE the microphone on your soundcard in control panels

It's a cell phone, but lemonadesoda says it doesn't matter. I didn't think it mattered.

I have in my hand a cylinder that I thought was made of iron (not graphite) from another cable. It's too small to fit around any of my wires without cutting the wires and slipping it on.

When I do move the phone away, the speakers will sometimes pick up some other signal from somewhere anyway.

I've heard of a fix involving wrapping part of the cable around a magnet, will that work?

I use the mic all the time, so no go on the muting.
