    Have you considered just buying and installing a PCI sound card bike Sounblaster? I t is likely much better that what you have and it is not all that expensive,especially via the internet. Most "onboard sound" is a comprimize based upon cost of the motherboard.

    Check newegg. com    or      Tiger. com 
     to name just two.

I believe you have a problem with the electronic section of your sound on your motherboard.If it were a software problem is would not have worked at all. The other option , other that adding a sound card is to replace the motherboard.. Even that is cheaper that trying to have someone find the problem and repair you presentl motherboard.

Low volume on

I'm sure that you have turned all the volume levels full blast. Go to the sound card itself and make sure that the ticks or bars are slid over to max as well. Not sure if your using headphones or speakers. Whichever your mainly using make sure that your set to its functionality in the type of speakers used. In some cases the head sets are different in volume than the speakers.
Sometimes although rare you may need to clean out the input jacks as well I use rubbing alcohol to do that let it dry a minute do not anything that will not disappear when sprayed on. The issue may be the movie your watching or online application your using or an upgrade you may need for Adobe flash player or Silverlight player all these things even bad speaker is out to ground.
I would also try some different speakers or headphones and last but not least redo the drivers for the sound card. This can often solve the matter as well. Other than all of this that is all I have on this issue. Maybe someone else has a better idea. John

Optiplix 780 soun problem

What kind of sound problem? Tell us what is happening?

Do you have the speakers plugged in the right port (light green port)? Have you checked to make sure the speakers are turned on and the volume is up? Have you looked at your Audio/Sound Properties to make sure the volume is up and the sound is not muted? Have you checked the device manager to make sure none of your sound/audio devices have a problem?

If you have a megaphone at the bottom right near the time Doubloe Click on it and make sure nothing is muted and volume is turned up. You can also get to the Audio Sound properties in the Control Panel, click Start/Control Panel and look for Audio/Sound. You can get there by clicking Start/Programs/Accessories/Entertainment/Volume Control.

My monitor goes blank while watching a movie on netflex about every 8 min very annoying . I jiggle the mouse and the picture comes back . sound ok . Help

Your computer is just going to sleep from what it sounds like.

Just get into the monitor/power saving/screen saver settings and make it so the monitor has a longer relay to shut down when there is no mouse/keyboard movement.

Audio soun do not working

1. Check to see if you have the volume control in the "off" position in the task bar (speaker icon) bottom left Of the Windows screen.
2. Go to the "device manager" to see if the sound card is working properly. check for updated sound card drivers. (See the helps menu to get to the device manager found usually in the "control panel"
3.Some sound cards are integrated with the mother board and can stop operating. Therefore a replacement sound card is needed. PCI possibly.
Contact your manufacturer for a possible replacement mother board or you may have to purchase a usb sound card.

My computer volume was suddenly stop working while i was watching movie, i checked all volume set ups but didn't work so please solve that problem

1. Was this a movie that came from a video store or was this movie on the hard drive?
2. How old is your PC and or your DVD optical drive?
3. This could be due to a bad burn ( the movie that is)
Some movies that are burned sometimes are interrupted and therefore will create a "halt" state on some DVD players and some PC DVD burners.
4. Also dirty DVD's will halt a movie in progress the laser is try to read the data through multiple finger prints or grease
5. Washing the DVD with dish washing liquid ( a drop or 2) and the rinsing and drying thoroughly usually renders the DVD playable again. Do not use hot water on the DVD disk it will warp the disk.

I was watching a movie then suddenly a spark came out and my woofer stopped working..also my pc volume also stopped working.i installed my motherboard cd..but still pc volume is not working.....

Where did this spark fly out from? The woofer or the computer? If it was the woofer, did you have it up too loud? Did you wire it correctly? If it was the computer, probably not, but if it was then sounds like your audio card fried itself. Maybe time for a new sound card. They make ones for PCI slots in the rear near the bottom of the pc.

Go to Dell's support page. Put in your computer's service tag. Choose download drivers and look over the list. Choose the audio device that is installed on your system. After you download it, navigate to the folder you saved it in and double click the installer.

Audio volume keeps changing by itself

No, the headphone output is designed for 2 speaker output. Just recently I had a customer who had no sound coming from the desktop speakers yet the headphones worked just fine.
I believe that your model has a sound circuit integrated into the motherboard. It may have a “plastic cap” covering the audio ports (next to the USB ports). If you remove the sound card and enable the integrated audio in the BIOS, you can check to see if the sound card is actually the problem.
