    I also was adjusting the monitor buttons and now the sound is not working and when I try to move the volume up and down it gives you that bong sound like when you get two many windows out at one time or went too fast for the computer to catch up, Please advise.

The electrical contact surfaces under the rubber buttons lose contact over time. I don't know if it's corrosion or some kind of build up. I fixed mine by disassembling the monitor, removing the button panel and cleaning the contacts with a pencil eraser. It works great now. The monitor is a real bear to take apart though. There are four hidden spring tabs on the sides of the bezel that are impossible to see. I groped with a very thin screwdriver blade and finally got them to release, but not without chipping some of the plastic.

Hi mam / sir the problem of my acer7715z its has n built in microphone and the volume of its speaker is to low how can i fix problem thanks

You can turn up the volume via the speaker icon in the lower right hand corner. If that doesn't get it to the level you'd like, then the speakers there aren't that powerful.

My advueu monitor has built in speakers which are not working now. do not know what is wrong

First--have the speakers worked before? If so, be sure the speaker wire is plugged into the green hole on the back of the computer and also plugged into the monitor.
Is there a volume control on the monitor? If so, be sure it's turned up.
Are you speakers muted? Check in the sounds icon in the control panel (there could also be a little picture of a speaker in the system tray. Many times people mute the speakers and forget they did it.
Also in the sounds area of the control panel, be sure the volume is turned up.

Need more volume on computer speakers

Buy yourself some stand alone speakers, a base & two side speakers, they cheap these days, base speaker has buit in amplifier & plugs into mains, or get surround sound 5speakers & a base, again mains powered, loud enough to annoy neighbours on full. Built in monitor speakers are renowned feeble tinny sounds. Right click speaker icon, bottom right, on your desktop toolbar, open volume control, ensure volume sliders set to max.

How on earth do I control the volume on a Dell E172FPB monitor?!!

What dell model is it. Most did not have speakers built in. There are clips to install an optional speaker bar on most dell monitors. But it has its own bolume control.

Monitor Built in Speaker Problm

Hi shah. It is most likely that the speaker's transformer is burnt. If its under warranty then the showroom guys should fix it for you as its covered under warranty. Otherwise you will need to take it apart remove the old transformer and install a new one. I strongly advise "if you are not familiar with electricals then better take the assistance of a qualified engineer".

Start with the obvious! Are all connections to PC connected? Be sure that the proper wires are connected to the proper plug in.
Next you may have to adjust the volume control thru Windows. Look for the small speaker icon at the bottom right (usually) of the screen. Double click, and be sure that all of the volume controls are "up" and be sure that none of them are "muted"

There also may be a volume control on the monitor, speaker assembly.

Good luck!

Go to your speaker icon in your task bar on right hand side and right click then on volume control. Go to file then select options/properties and then scroll down to the microphone on the show volume controls box and tick it. The microphone volume slider should now show and make sure the mute is unticked.
