I have no sound on my PC, not sure if it jack, or board, or other

I can't get any sound on my PC. I've tried a couple of different speakers that work on other computers, but no luck on this one. I'm wondering how I can determine where the error is? We can plug headphones into the headphone jack on the front of the PC and can hear sound that way. But plugging speakers into the back jack doesn't work. SInce the headphone jack generates sound, is it likely that I could get some speakers that connect via the USB port that would work?

no sound can be related to chipset drivers ...maybe yours needs updating...

Since you get sound from the headphone jack in front, this isn't an issue with the actual audio chip, but with the connections.   It's likely that the front jack isn't releasing contact when you unplug a device from it, so the sound always goes to the front.

You could simply plug your speakers into that jack;  or you could add a USB audio device, or an add-in sound card if you'd prefer to have audio available on the rear of the PC.    Alternatively, if you don't mind disassembling the front panel, you could replace the front panel jacks -- but this is a fairly delicate operation, so if you're not comfortable with it, don't do it.

This type of very cheap device will do that.

Have you tried plugging the speakers into the headphone jack at the front? You should get some sound.

Have you tried plugging the headphones into the line out at the rear? (Keep the headphones out of your ears while plugging them in)

It can also be a driver setting. Many sound drivers allow you to map the audio plugs to different devices. So open your audio driver's utility and check the settings there.

Apparently I had two sets of bad speakers. Or maybe, as garycase suggested, the front jack wasn't releasing the connection. Anyways, the speakers are working now. Thanks all for your help!
