I stopped having sound coming from the speakers. I checked and we are not on mute, and the volume is turned up high.

Are you plugging the external speakers into the right port? Try plugging them into the Headphone port if there is no external speaker port. Make sure you have the external speakers turned on and the volume turned up. Also make sure you have the software in the computer to have the volume turned up and not muted. Check the audio sound properties and make sure the volume is turned up and not on mute.

Click Start/Control Panel then look for Audio or Sound and check the volume.

You can also click the megaphone at the bottom right near the time to adjust the volume and check for mute.

Hello.
This is a very frequent case and it is not rare.
These speakers usually are not that much of a high quality, so the chances that these speakers (or one of them) will stop working is very high.
First of all, to check that hte speaker isn't corrupted, try making sure that all the necessary cables are properly put in their places:
Check that the two speakers are connected to each other (usually a cable coming out of the back of the speakers).

Secondly, check that your computer has not muted the right speaker:
Go to Start -> Control Panel -> Sound and Audio Devices -> Click "Speaker Volume..." button under the Speaker Settings frame -> Set all volumes to the max (Drag the slider with the mouse to the high right)

If none of the solutions worked, then there's a 99% chance that the right speaker has been corrupted or is malfunctioned. If so, I recommend buying a higher quality set of speakers.

Good luck.

the small speakers in the projector can't handle high volume, so the speakers may be shot.

verify whit hear phones if is correct audio the problem is not in the computer...also check instalation driver sound is sound max for your computer

First make sure your sound cards are working properly. 1) Check the master volume of your PC. Go to start menu, control panel, sounds speech and audio devices, sounds and audio devices - i) In volume tab click the speaker volume and check whether all the left, right, etc.. volumes are in medium or high. ii) In audio tab click the volume tab of sound playback and make sure that the master volume is not in mute and all the volumes are either in medium level or at 100%. After making these changes try playing any music. Even if the problem persists go and get your sound card checked in an authorised service centre.

Thanks & Regards,

Have you tried going into the speaker settings? We'll assume with a new PC you have Vista installed, click the speaker icon on the right side of the tray, and selecting "Mixer" will enable access to volume control for the output devices and for applications.

If no speaker icon is visible To check the volume controls in Windows Vista, click Start and then click Control Panel. Choose Hardware And Sound and then click Adjust System Volume under the Sound section. The Volume Mixer window will open, and you should see volume sliders for Device and Applications. Click and drag the sliders to view the volume level percentages. If the speaker icons show a circle with a red slash, click the icon so the speakers are no longer muted.

Furthermore, you’ll want to double-check all of your master volume and mute settings.

Did it stop working or has it ever worked before?

Make sure there is a cable running from your computer to the monitor's integrated speakers. It should go from a green 3.5mm output jack at the back of the computer to one the same size in the back of the monitor. If the cable is there and still no sound, double check the connection, make sure they are plugged in securely at both ends. Be sure that headphones are not plugged into the computer at the same time or audio will only come out through the headphones.

Make sure the audio is not muted. There is a mute in possibly 3 places. One spot is the application audio: if you're trying to play from Windows Media Player, make sure the audio is not muted near the slider and that the volume is loud enough to hear.
Second place is the system volume. In the Control Panel, Audio (Start menu, Settings, Control Panel, Audio component) you can check the volume and mute of the system volume.
Third location is the monitor speakers. There may be a way in the monitor's menu to adjust the volume for the speakers. Make sure it is high enough to be audible.

If all of those are unmuted and high, you might try replacing the audio cable. Also reboot the computer with the audio cable plugged in where it should be. (Sometimes high-def digital audio can be quirky). Next try plugging in a pair of headphones into the front of the computer and see if you're getting any sound through there.

Those steps should help you diagnose the problem. If not, just post back with what you found out through these steps.

you might want to look into one of two options... either an external sound card, or a keyboard that has mltimedia buttons on it.

If you go with the former, the Audigy 2 NX external sound card might be want you are looking for. It's small and has volume controls right on the top. Granted, it is overkill if you just want simple volume control. However, if you don't have a high-end sound card already, it could be a nice addition to your desk..?

I think its the flyback and its starting to leak. this is a component responsible for the high voltage of your tv set. always observe safety in dealing with this. Have it check by a qualified technician. Good luck!
