Do the headphones work in the same input where you are using the speakers? Open the Control Panel and Sounds and make sure everything is turned reasonably up and not muted. Also, in Device Manager you might right click on your sound card and try "update driver"

I bought a pair of HP headphones and when I plugged them in they installed themselves. They worked fine for a while, but for some reason they stopped working. When I unplugged the headphones, I realized...

no computer listed, no OS stated, now THAT is a challenge. no?
this is common
it causes the system to have 2 sounds systems
that head phone is not that, its Head phones and a USB sound chip. (2 sounds systems are there now)

so you have 2 choices. (confuses me wife too)
1:; in device manager turn off the PC sound car, "disable it"
2: or learn how to run both using the sound, applit in the task stray.

right click speaker icon in tray
the pick (windows10) play back device
and last pick (which one you want now, new heads or stock speaker)

When switched on a humming sound comes out of all speakers,no audio can be heared when a cd is played.

check all jack plugs are in the correct places and speaker connection wires too.try turning your tuner on to test the speakers that way for sound,if sound is heard through the speakers it could be a cd malfunction.if nothing works contact your dealer.

I use the system in my room for my i pod and one day it just stopped working. when i plug it in and try to turn it on, nothing happens and there is no green light...whats wrong?

This sounds like the power adapter for your speakers is not working.

If you have some electronics experience you can test your adapter with a multimeter or maybe have someone else do it for you.

If you plan to replace the adapter, (if it is the adapter that is not working) be sure to use the same AMP and Voltage rating that is on the original.

Right speaker doesnt have sound

1ST.-The right jack could be damaged!!
Usually, there is a [+} posaitve & [-] negative input\output to speaker connections. Not all [-]neg. is ground.Sometimes the [+] pos. is grounded. [The exception to the rule is that u SEE the black wire going to ground] the reason I am letting u know this is that u can test the INSIDES of the sound system.
If u can get inside of the unit. Cut the left speaker output [+] posative from both outputs. criss\cross wires.Place left speaker output to right speaker jack[ that does not work!!] & visa versa.If the [LEFT Output] stops working after u plug in the speakers,the internal RIGHT output is damaged. NEEDS TO BE TESTED
If nothing nothing changes.The left still works & the right still does not work, then it is the jack (shorted ?, opened internally ?)

Sound problem with LG LHT754 theater system

Hold down "2" on the remote simultaneous to "stop" on the receiver. In a couple of seconds you will see something appear on the display. OPO-63? Anyway, repeat the process again when you see that. The system will reset. This will also take care of the inability to switch to AUX or Ipod.

No Sound

carefully plug back the minijack for the speaker at the out or spk,
normally the sound card has three ports 1. for MIC 2. LINE IN 3.OUT (SPK) - SPEAKER.
carefully plug the minijack for the speaker into the third one - OUT (SPK) - SPEAKER.
in pluging it in, first put on a media clip on the windows media player and carefully plug in the minijack for the speaker and surely you will hear sound.

My hp speakers wont work

Sample testing is usually a firmware built into the monitor amplifier ie the monitor is testing itself. you problem possibly lies with the computer sound system. Tell me more about this. Is it an 'On-board' sound card or separate PCI card. You can determine this by looking at the back of the computer- if all the connectors - sound- PS2 and USB are in the same panel - then it is an on-board system. If the sound is separate in one of the card position then it is a PCI card. The possibility is the sound system needs setting up- check your computer paperwork/manual and utilities disk for Audio drivers. Come back with some answers
