Unplugged speakers, plugged em in -- now I don't get ANY sound
My girlfriend unplugged my PC speakers for her iPod, then plugged em back in. Now there's no sound. They are powered up (power light is on), plugged in the right port (same one as always), and aren't muted. To make matters worse, now my headphones won't even play sound when plugged directly into the PC headphone jack! What happened?

1. check the power, is the LED indicator light when you turn on the power?
2. assuming the power is ok, unplug the phone plug from the computer, plug it to an ipod or any mp3 player's phone jack, still no sound? here are the possible causes:
a) broken internal copper conductor from the phone plug,
b) busted amplifier chip
if you have basic electronics knowledge, these multimedia speakers are easy to repair, otherwise replace the whole unit. ;-)
you need to make sure youre getting a signal from the source, RCA's I suppose. Check for loose connections or broken wires. make sure to have 12v+ on power and remote inputs at amp...proper ground too. Lastly, check your ohm loads at speakers, maybe one is about dead. make sure crossover settings are correct.
Although some monitors have built in speakers, most people have stand alone speakers. If the old monitor had built in speakers and now it is unplugged you won't hear sound. Even if the speaker cable is still plugged into the sound output on the back of your computer, the monitor must be plugged into an electrical outlet to have power.
I'd recommend buying a new set of external speakers if this is the situation.
If you never had speakers built into the monitor then normally changing monitors would make no difference whatever. The only explanation that makes sense under those conditions is that in the process of replacing the monitor, you dislodged the speaker jack from the sound output on the back of the computer.
Make sure your external speakers have electrical power plugged in, the power is on (green light on at least one speaker lights up) and the volume on the speakers is at least half way up.
Unplug the speaker from whatever hole it is plugged into and plug it firmly back in and test sound.
If still no sound other than some static on the speakers, try every single hole on the back of the computer that the jack will fit properly and test for sound.
Sounds like he forgot to plug back in the sound cable when he took his iPod out. Simple fix for this. Pull out the desktop box (computer) and find what should be a green sound cable and plug it into a green port in the back of your computer. If your having trouble as to what it looks like, get your son to identify what he took out of your desktop to listen to his iPod and plug it back in. Also check that your speakers are turned on and are up on the speakers and on your desktop, which you can find in the bottom right hand corner near your desktop clock. The icon looks like a speaker and just click on it once and make sure its up all the way and not muted. Let me know if this works or not
if no light came from the speakers then something is corrupted inside them .. you have to check the power source and power cable of the speakers first ... if everything is fine then the speakers are corrupted from inside
