My desktop speakers not working but cable all plugged in and audio device working.

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.

The light green speaker audio cable should go to the light green connector on the back of your desktop not the disk drive or monitor!

Make sure speakers are on ! Make sure speakers or headphones work in the first place on another device.

Plug the cable from your speakers or headphone's into the green audio port on the computer, if that fails, possible driver problems ?

Some things you need to check

1. Cable connection of the speaker to your computer and the power cable if its plug in correctly. Normally the Audio cable of the speaker is plugged into the green audio port on the computer.

2. You speaker is on mute. Check the speaker icon located on the lower left side of you desktop. If its on mute then try to un-mute the volume and test the speaker.

3. The driver is not installed properly. Check the device manager if there is a Question/Exclamation mark on the Audio devices.

4 If everything are Ok. try to plug the Audio cable of the speaker to any of your Portable sound devices like Ipod. If that still does not work then you need to replace the soundbar. Contact Dell for a free replacement if still under warranty.

Thank you.. 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.

If you're using Windows XP, go to the Control Panel, then double-click on Sound, then go to the Audio tab and make sure the playback device is set to your Realtek output.

If you're using Windows Vista, go to Control Panel and click on Hardware and Sound, then click on Sound. Make sure your Realtek device is selected with a green check mark. If it isn't, just click on it and then click the Set as Default button down below. Vista sound configuration is kinda quirky, and it does do some kind of detection when you plug a cable into an audio jack, so you might leave this screen up while you plug your speakers into the green audio jack in the sound card and see if it pops anything weird up.

You will pobably need to load the driver for your system.

Go to Dell Support and click on the Drivers & Downloads box.

Follow the prompts to select your specific system model. you will end up at a page that lists all the available drivers for your computer. Click the + sign next to "Audio" and you can select "Download Now".

When the download window opens, select "Install".

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.

make sure that the speaker cables colored plug match that of what is on the back of the computer, also make sure that the volume control console is set for the correct output. Lastly, if none of these work, try uninstalling the audio device by right clicking my computer, select properties, go to hardware, and click device manager and thenright click the audio device and click uninstall, then reboot, and follow the instructions that come up when the computer reboots, and see if that works.
