My laptop sound doesn't work

on board audio... remove all traces of software (uninstall sound card software) remove device (uninstall sound device in device manager)

restart computer, if it finds sound device, install software.... if it doesn't, turn off sound card in CMOS and install daugter card sound board dependant on available expansion slots

Here is the link, some of the text is in Danish, but just press the download tab, and all of the useful text is in english.http://www.asus.dk/Motherboards/Intel_Socket_478/P4S800MX/#downloadGlobal
If you already have tried this download, are you sure this isn't the se version of the motherboard?
Regarding the usb and sound; first of all have you installed al the drivers supplied with the motherboard? If you have, then have you connected the internal usb pins to the external ports and tried every usb port including those on the back?
Unfortunately that is what I can suggest at this point... If that doesn't work, and updating the bios doesn't work, then I suggest resetting the motherboard.
Hope this helps

Hello,

This can often be as simple as the speakers being unplugged, plugged into the wrong jacks, or powered off, so don't overlook the obvious and check to be sure. Also check the volume controls in Windows or your application to see that they are turned up and not muted. When you are sure the volume is turned up, the speakers have power and are plugged in, and the speaker configuration is correctly identified in Windows (some audio hardware uses a proprietary mixer control for this job), you need to verify whether the problem is with the speakers or the sound card. Connect different known-good speakers and see whether they work. If they don't, the issue is in the sound card-possibly the configuration of the card is incorrect or the card itself is defective. The first thing to try is clearing the ESCD in the BIOS Setup. This essentially forces the plug-and-play routines to reconfigure the system, which can resolve any conflicts. If this doesn't help, try removing and reinstalling the sound card drivers. Finally, if that doesn't help, physically remove and replace the card from the system. You might try replacing it first in the same slot and then in a different slot because timing issues can sometimes exist from one slot to the next. If that doesn't work, you must try replacing the card. If the sound "card" really isn't a card but is integrated into the motherboard, first try the ESCD reset and driver re installation. Then, if that doesn't work, you have to try disabling the integrated sound and perhaps installing a replacement card.

I hope one of these solutions help.

your teacher forgot to put driver on your sound card, you can install it by yourself by knowing the model of *********** board try using CPUZ, download it and search the motherboard model. then search the driver of that motherboard in google search.just download the sound driver and install.

a l'ill more explanation required have u installed audio drivers? if not then install correct audio driver from the CD given with your motherboard.

You should try to start your computer without the battery installed. If that doesn't work, you should try another power supply. If that doesn't either do the trick, it could be the motherboard causing the trouble.

Try to reattach your sound card. It will solve the problem. If it doesn't work you can format your computer or clean the viruses on your computer. If problem still occurs change the sound card.

i dont at all think that it is a problem. If windows 7 is not detecting your built-in via 1708s sound card then try installing the latest drivers from the gigabyte website or the via official website. If that doesn't work then try installing an add-on sound card that you can buy from anywhere.

Hello vatsala,

Try downloading and installing the latest sound drive available for your motherboard. Here is the link.

If that doesn’t work, try using another set of speakers to make sure it’s not your speakers that are bad and if that doesn't work, you may have a bad sound card and will need to put in new sound card.

Sincerely,

Agent Xiong

Did you install the most recent drivers?
