Question: 2 power sources?

I just got a new computer, and the speaker cord has me curious.

It looks like any other I've ever had, but there is a USB connector split off from the regular jack right at the end. Do I choose one or the other, or do I plug them both in? In either event, I have no audio at present. Mahalo in advance.

Model number and maker would be helpful. Photos are always good too.

You should be able to plug in the regular (1/8" stereo mini) plug to get your sound. The USB cord might be to let you control some computer feature with a knob or other input on the speakers. It might also be for a power supply. Do the speakers have their own AC adaptor? If not, that's probably it.

It may be for powering the speakers. Can you be more specific about what wires you have exactly, and what's plugged in to where, as well as what the ends look like. Specifically with the USB, does that end look just like the USB cord on a mouse or keyboard, or is it the small kind like you'd plug into a camera?

Instead of plugging the speaker into a wall for power, it draws power from the USB jack.

It's a Gateway DX442B, and the speakers identify themselves as sigma tel high definition codec. It is the same type USB connector as the mouse and printer, and the familiar green color coded speaker jack.

Ok pretty much two options then: either the speakers have a set of female USB ports and it's supposed to be a convenience feature, i.e., speakers combined with a USB hub, or it's for powering the speakers from the USB 5V. Given that your speakers aren't working, I'd guess power is more likely. Plug it in to a powered USB port and see if that fixes it.

It's for power. At work when we install new speakers, they're this type. it saves you from having a power brick hanging off your surge protector.

No, that's the audio card in your computer.

Yep.. Gateway's website says "USB Speakers"... so I'd be willing to bet quite a bit of money that the USB connector is for POWER...

You'll need to have BOTH the green 1/8inch audio jack plugged in.. as well as the USB connector in order to hear sound.
