Extended speaker wire, now no sound
Dervacumen:
Well, I had to extend the wire on my amplified speakers a foot, so I cut the wire, added a 1 foot section, made sure the polarity was correct and plugged the 3.5mm jack back in to my soundcard. I have no sound.
When I run my speaker test (software that generates white noise) and I turn the volume all the way up to max, I can very faintly hear white noise coming from the speakers.
When I plug another set of speakers in to the jack the sound is fine, so something is amiss with my speakers.
The speakers have a power cord which is plugged in and the power light on the speaker indicates they have power. The speakers are of the 2.0 variety, with the power and 3.5mm cords running from one speaker, and a second wire running out to connect the second speaker, typical of most older style computer speaker systems.
So what will cause this? The way the speakers are mounted in the cabinet, it's very hard to make sure the volume adjustment is all the way to maximum, however the volume is controlled by a wheel and I know that if I turn it to the left I can hear the faint white noise diminish, and when I turn it to the right I can hear the white noise increase slightly. So I don't think I have the volume on the speaker down, at least not to the point that it would be almost inaudible.
When I load a ROM I hear nothing.
Possible that I have something wired incorrectly? The wire I cut is the one that runs from the 3.5mm line-in jack on my sound card to the first speaker. I would have thought I could just extend this like any other wire I extend. Two conductors.
Duhhh.
kegger:
Take a good look at the wire it self, if the control for the volume is in line with the wires then those speaker wires may be special and contain possibly more then one and can possibly be shielded. I ran into the same issue with a set of Cambridge soundworks 2.1 for my cab and ended up ordering a whole new volume control cable because there was no way to actually splice the tiny wires I cut which really looked like one normal speaker wire.

There should be 3 conductors in that wire. One may be a braid/foil shield being used as the ground conductor. It would need to be extended as well.
Special extension cables are made for this and can be had for a couple bucks online. Would be far easier to just use one of these.

there is a wire for left, one for right, and one for the ground

That's what I've come to realize, and should have known since it makes sense. I was wondering what that thin thread was. Apparently it was the ground. Now that's gonna be an interesting task. And I thought my ribbon cable was small. I wish my eyes were better equipped to deal with such small things nowadays.
Replacing the cable isn't really an option in this case. It's either fix this one or shove a new set of speakers in the cab somewhere. #&(%^%&!.
