Speaker quit working

These are analog speakers and do not need a driver. First, make sure they're plugged into the speaker/headphone jack and not the microphone jack. Second, make sure the computer's sound output is enabled and set the headphone/speaker jack. Third, verify that the sound output is working by plugging in a headphone set or a different pair of speakers. If the computer sound checks out, the speaker cable is bad or the power supply is not working.

Check your computer set up. It might have switched the speakers off when you unplugged it. If that doesn't work it could be the jack plug itself. But often you can tell it's faulty due to if it's moved it might come back on again.

No the headphone jack doesn't disable the speakers. There are two switches in the lower middle of the receiver that are labeled speaker A and B. Pushing one of these should disconnect the speakers from the receiver.

Hello,

Are you plugging the sub into a 3.5mm jack or USB?
Have you tried to plug the sub into the speaker jack?
The sub works on another computer?

Bad sub or bad jack?

I hope this helps!

If the stereo jack works, then there is no problem with the sound card or its drivers. Your speakers have played their last, most likely some internal wiring broken as speakers themselves rarely just quit.

Have u tried pressing the FN and F5 key at the same time or opening the speaker icon near the clock and checking the settings?

desktops now a days have more than one plug for the speakers. try playing some music and play which hole works.

if there is a 5.1 or surround on the desktop then most likely the light green jack isnt stereo out but rather unamplified signal. thus when you plug head phones into it the internal amp drives the headphones, but wants the computer to drive the speakers.

try plugging it into the black one... or play pick a hole till it works.

go to the control pannel, then go to sounds and audio devices, then click the audio tab across the top. under sound playback, choose your speakers as the default device. solution only works like this for windows xp. good luck

See if it works with the headphone jack instead of speakers.

If the sound is intermittant on the headphone jack too then the headphone jack is broken causing the speakers not to work. You could probably find a place to solder the jack.

If it works fine on headphones then either the speakers are bad or the amplifier on the mainboard has failed.

I believe this is a wiring incompatibility problem. The reason I say this is because when the mp3 player is out the jack which contains switches engages the front L&R and the Rear L&R, when the plug is inserted into the jack the jack switches should remove the audio input to the amplifier and replace it with the audio from the mp3 player. The switches should then send sound to the front L&R and the Rear L&R but the only change should be that the mp3 player is switched in instead of the audio from the raido unit. what is happening is that the jack switches are only switching in the front L&R speakers. This just might be a function of the unit. check the owners manual. here is a site that has the manual: http://www.docs.sony.com/release/XAV7W.PDF
