Speaker Problem

by cv4stm / January 1, 2007 12:27 AM PST

Last Christmas I purchased a set of Altec Lansing 5.1 surround sound speakers

In the last couple of days, I noticed that my left front and left rear speakers are not working.

I have tried to unplug and replug everything, and I have checked the settings on my computer.

Neither of these fixed the problem, so now I ask, what is wrong with my speakers and how can I fix them?

First we test...

At this point we don't know if the speakers or PC is faulty. Where and what else can be used to test the speakers?

ok, I tried the speakers with my iPod and they worked.

So, I know it is something in the computer, but I don't know what.

Earbuds, head phones and Speaker settings?

Test the audio out jack with a headphone. If you set the speader type to 2.1 then and if the channel is dead you may have a dead audio on the PC. I usually test this with headphones and a Linux boot CD (Knoppix.)

At least we know to look at the PC here so that's progress. Now we need to figure out if it's the PC hardware or the software.

Ya. so I plugged headphones into the audio out jack and getting no sound in the left headphone.

So I pretty much need a new soundcard?

So, I plugged my speaker audio out cable into the headphone jack in the front of my computer and it seems to be working.

I guess the headphone jack is just considered a headphone jack cause it overrules the speaker one in the back and the surround speakers worked fine this way as well.

Thanks for the help man.

Is it the jack?

If so I could remove the mainboard and reflow the solder to the jack or replace just that. Remember I'm an electronics designer so such is not a big deal here.

But for many it can be much cheaper and less harrowing to disable the onboard sound card in the BIOS and install a new sound card.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
