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.

My computer is a SyncMasterP2570HD i cant get any sound to come out but it is detecting sound how do i fix it


The Samsung SyncMaster P2570hd is a monitor with speakers; it isn't the computer itself. I'll assume that you are dealing with a computer connected to the monitor and not a set-top box. Make sure that Mute is not enabled on the computer. There should be an icon on the lower right hand side of a Windows desktop. If the mute is enabled, it will have a red circle with a diagonal line through it. Left click on the icon to remove the mute (change the volume or click on the mute icon). Test the monitor's speakers by connecting it to another device with known good audio output.

Next how are you connecting the monitor to the computer (VGA, DVI or HDMI)? If you are using VGA or DVI (including DVI to HDMI), you need to connect an audio patch cable (3.5 mm) between the speaker (green port on the back of a sound card) or headphone jack of the computer and the audio input jack of the monitor. The audio input jack is between the DVI and VGA ports. You can test the output of the speaker jack on the computer with regular computer speakers. Plug in the power cord (or USB cable) for powered speakers. If the free-standing speakers work, check the volume setting on the monitor with the +/- buttons to the right of the menu button. Do not press menu first, though. If that doesn't solve the problem, continue using the separate speakers. (Unless the monitor is still under warranty, it usually isn't worth taking apart a monitor to replace the speakers. You may be able find replacement parts online.)

If you are using an HDMI cable, check the output audio setting to see if the HDMI audio is available. For Windows, click on Start > Control Panel > Hardware and Sound (Windows 7). Then click on Manage Audio Devices under Sound. In the Playback tab, check what available audio devices you have. Make the HDMI the default device by right-clicking on it and selecting Make this the default device. (Other versions of Windows will a slightly different route to this panel.) You may need to restart the computer to get the audio signal on the HDMI cable after setting this. Note: not all video cards/computers support HDMI audio. If you don't see HDMI listed in the Playback devices, connect an audio patch cable as with a VGA or DVI cable, described above. Use stand-alone speakers if the monitor's speakers are bad.

I hope this helps.

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.

We have older speakers that came with our computer, and we just moved and since we've moved no sound has come out of the speakers. i have checked a million times and everything's plugged in. i...


First check if the driver for your speakers is up to date. For all we know maibe something that was installed automaticaly or by some one might be interfearing with them. Go to the Window menu, click on Conrol Panel, click on speaker settings, and check to see if anything looks off (like everything is gray and you can't really select anything). If everything seems ok check all the volume settings. Remember there are 3 things that control the volume on the speakers. 1: the nob on the speakers; 2: the volume on your desktop (lower right side next to the clock); 3: the volume on the program you are using (like windows media player). Another thing to remember is some computers come with a mute button (ether on the keyboard or monitor. If your computer has a play/skip/stop buttons it most likely has a mute button. Oh, and some computers have a volume nob next to the CD/DVD player (where you put in disks). Maibe some one turned it down as they grabed to move it. Make sure it's also turned up. If they're all turned up then most likely something got bumped loose during the move. In wich case you'll have to open it up and check the conections. It'd be a good idea to test some one elses speakers so you'll know if it's the computer or the speakers...or you could try pluging in the speakers you have into something else (like an MP3 Player).

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.
