Speakers work...just not when plugged into desktop

Do you have the AC adapter plugged into a live outlet and have you turned on the speakers? Make sure that the speaker signal cable is plugged into the correct port on your computer (the lime green port on a desktop). Check that the correct audio driver is installed for your computer. (With Windows 8, use the Device Manager to check. From the Start Screen, type in Device Manager. Click on Settings and then select Device Manager. Alternatively, Windows key+C on the desktop. Select Settings and then Control Panel. You can find the Device Manager under System and Security or Hardware and Sound.) Scroll down to the Audio devices. Expand the section and look for a red triangle with an X or a yellow triangle with an exclamation point. Try updating the driver (check with the manufacturer of your computer for the latest driver). Even if you don't see the error triangle, try reinstalling the latest driver.

Next check if the speakers work on another computer. If they don't work, the audio cable may be damaged. Try a different set of computer speakers on your computer.
If other known good speakers do not work and the correct audio drivers have been installed, check the audio output devices. Go to the Control Panel > Hardware and Sound page (as described above). Choose Manage Audio Devices. Check if the HDMI port is set as the default audio device. Disable it for a bit (right click on the device) . Sometimes when a new video card is installed, the audio device defaults to this port. This messes up the drivers for the regular audio.) Reboot the computer and then try reinstalling the audio driver. Reboot again.
If it still fails, there is probably something wrong with the audio device hardware. If you are using an add-on sound card, try disabling it and using the motherboard audio device. (A number of add-on sound cards didn't work well with Win7 or Win8. The on-board audio drivers worked better.) If you are using the motherboard audio on a desktop, try an add-on sound card. (Check for Windows 8 compatibility (drivers) before selecting any card.)

I hope this helps.

Make sure your speakers actually work by unplugging the speaker jack, turn the volume up the high, wet your fingers and touch all the connections at the same time. You should get a ground humm. If you do get the humm then the next step is to go to my computer, right click on it and go to "properties". Depending on your operating system, you have to locate "Device Manager". Once open look for any devices that have a mark on them indicating that they are not functioning (in this case it would be in your sound device). Reinstall the drivers for the sound card if they show as not working, or go to the drivers tab of the sound card properties and see if you can fall back to a previous driver (windows update supplies driver updates that in many cases prove to be the wrong one, don't use Windows update for drivers). If everything looks good for the sound card in the device manager and your speakers are working then you may need to install a sound card. Good luck

The LG W2343T does not have speakers. So you can't plug in a 3.5 mm audio patch cable between the computer's line out or headphone jack and the monitor. (Similarly, other devices can't provide sound to the monitor.)

Are you using a desktop or a laptop? If you have a laptop, make sure that the correct audio drivers are loaded for your OS and make sure that the audio isn't muted (look in the lower right on a Windows system in the tray for the speaker icon). On an HP laptop, we had to use the Component Services (Control Panel > System and Security > Administrative tools > Component Services > Services in Windows 7) and stop all audio services and restart them. Then reboot the computer to use the internal speakers at a reasonable volume.

For any unit with external speakers (required for a desktop, optional for a laptop) , connect the speakers to the audio out port (green for 3.5 mm for single connection speakers, see the manual for other speakers) or the headset port. Next make sure that the device drivers are loaded and correct for your sound card (or motherboard audio). (Control Panel > Hardware and Sound > Device Manager). If your sound isn't active, look at the Sound header. Then choose Manage Audio Devices and the Playback tab to select the desired speaker option. (Again these are for Windows 7).

If you still have no audio, make sure that the speakers have power (USB cord or AC adapter plugged in depending on the speakers). If it is USB powered, try a different port or a powered hub. If you have an AC adapter, check if it is warm. Some speakers have power/volume knobs. So check if they are on (if there is an LED, that is an easy check). If still no audio, try a different audio patch cable, if possible. Otherwise, try different speakers. There may be a damaged wire preventing the speakers from working. Depending on the problem and if your speakers are under warranty, it may be worth fixing or not.

Documentation for the monitor is available here: http://www.lg.com/us/computer-products/monitors/LG-lcd-monitor-W2343T-PF.jsp . Click on the Support tab.

If you want to use a stereo receiver with RCA audio inputs, you'll need an adapter or a 3.5 mm to RCA m/m audio cable.

I hope this helps.

Several possibilities come to mind: speakers have failed (self-powered speakers have bad power brick, cable damaged, etc), speakers plugged into the wrong port (audio in instead of audio out), audio card or driver has failed.

If you recently had to restore your OS (or do a roll-back to a "known" good configuration), check your audio device (make and model) and make sure you have the latest driver installed. (Look at the website for your computer if it is a prebuilt system or look up your motherboard if it is an on-board audio device.) The device manager might have a yellow exclamation mark on the audio device if this is the issue (access from the Windows Control Panel)

Check for bad speakers by trying another set of speakers or plugging them into another computer. (Swap cables if that is possible.)

I hope this helps.

Things to check:

1. Ensure you are plugging into the correct port. Some systems have both integrated audio and and expansion sound card. If it has both, the expansion card should be the port to connect the speakers. Generally all desktops use Green as the speaker jack color.
2. Ensure the volume control is not muted. Set volume for 75%
3. Ensure if the audio is integrated, that the audio is enabled in the BIOS
4. in Control Panel, Sounds and Audio devices, make sure the sound card is the default playback device. Also ensure that Stereo desktop speakers are selected as the speaker tyoe.

have you plugged the speakers in to the right ports? for sound IN and OUT

so lets do a quick follow here sound from TV is AUDIO OUT PLUG say red (L)and yellow (R) to SPEAKER L and R Power to speakers is on and the volume is set to medium or at least not to zero. Play something through the line are the speakers working, is ther eany humm or nasty roiugh humming bbbrp sound? No? is there a red light on speakers to indicate they have power? no? check that there is a on off switch at the rear and it is set to on.

If they are new and you have folloowed the procedure I woulod be having them checked by the shop you bought them from.

You might have to reinstall the software that came with the speakers since you had to wipe your computer clean when the virus was on there. The speakers will not work until the software is installed back on your computer.

Maybe your audio device not compatible to your speaker, try update your audio device.
