Speakers don't work

My monitor speakers just stopped working. I know it's not the computer itself because I've checked to make sure all of the right devices are on and it's not on mute.

I cannot hear any sound from my Dell monitor 1702FP. Are there speakers installed within the monitor?. VGA cable is connected. When I use a spare monitor using the VGA cable the sound is loud and clear. ...


The Dell 1702FP doesn't have speakers.The specs of the Dell 1702FP are available here: http://support.dell.com/support/edocs/monitors/1702fp/en/specs.htm . (BTW neither does the Dell 1704FPT.) However, some Dell monitors can have a sound bar (speaker set-up) mounted on the monitor.

VGA cables don't carry sound. Check if a second cable (an audio patch cable is connected to the computer and the second monitor). (There are some cables that actually bundle the 3.5 mm patch cable with the video cable for convenience. (I've seen a number of DVI cables with that bundle option.) The plugs will separate into separate units at each end.

Other monitors do have speakers built in - look for a 3.5 mm audio input jack with the rest of the input connections on your monitor. There are some monitors that accept an HDMI input with a 3.5 mm audio out jack; these monitors don't have speakers and thus are enabling a daisy chain to connect the speakers to the monitor. So you do need to be careful and look for the audio in label.

You can attach a set of speakers to your computer using the audio out (look for a lime green 3.5 mm jack on the back of a desktop). For laptops or to use the front audio ports, look for a headphone jack.

I hope this helps. Please add a comment with more information about your monitor and computer for additional assistance.

No Sound LGW234T-PF


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.

Is my AOC 9170 monitor compatible with HP Pavillion 6523W Windows 7? Does this monitor have built in speakers?


Hi there,

I am not sure about the speakers. The best way to tell if it has speakers is if you can physically see them. They are usually located at the bottom of the monitor and they look like little screens on either side of it. If it doesn't have HDMI or a line in jack (speaker plug) that you can see then it won't have built in speakers for sure.

If the monitor has the right connections to plug into your HP computer, which it should. Then it will work with your computer. Your computer has both VGA and DVI monitor connections on it so either of these should work as long as your monitor has the connections (which it should have at least one).

I have lost my speakers on the monitor. Using Microsoft XP, they were working but now they are not. Did some driver updates then lost the sound on the monitor. Checking the control panel indicates that...


Sounds like you've lost audio output from the sound card. Unplug the audio cable from the sound card and plug in a set of ear buds or headphones. If you don't get any sound your driver's not working. Try reinstalling the old driver.

My View Sonic monitor speakers were working fine until yesterday. There is a static sound coming from them now.


Double check all your connections to start with and make sure the lead for the speakers is plugged into the GREEN port on your computer.

Also and i know this may sound silly.

Check that you don't have cell phones or wireless phones , baby alarms too near the computer or speakers.

My speakers give me advance warning of when my cell phone is going to ring if I have it too close to my computer !

Hannspree Monitor speakers wont work


I don't know if I caused the problem or not. I hooked up my new Hannspree HF237 monitor to my HP pc, and the sound wasn't loud enough so I hooked up my external speakers, and got nothing. So I disabled one without the other, and still got nothing. Now I can't even get the monitor's sound to come back on. Any ideas?

No sound coming from speakers.


Did you run the audio cable from the computer to the monitor. If not you must have that for the speakers to work. If yes can you verify computer output with another pair of speakers to narrow it down to computer or monitor. If it is the monitor built in speakers that are the problem reply and we can go through a procedure to get them working.
