I have this problem with my computer,suddently it stopped having sound from the speakers.I know that it has no sound card because the motherboard has a sound card.My motherboard is ABIT guru 18 bit,NV939-1,00M.The speakers cables are at the correct receptions(input sources).I tried other speakers in case the one i have are broken but still nothing.Any ideas what might be the problem?It is really frustrating not hearing anything!I havent made any adjustments at the volume control,no mute options are on.Please help!

First of all check with Windows sound control that the sound level is where it should be, that the sound isn't muted for for applications, wave and midi. Then make sure that the speakers are plugged into the right socket. The last option is to reinstall the audio drivers.

Thanks!I ckecked the windows sound control(at the control panel,right?sound and audio devices and itsnt on mute.Where is wave and midi?The speakers are connected to the correct socket.I reinstalled the ABIT software and nothing,no sound.

Double click on the speaker symbol on the tack bar. Press file(I think, don't have XP any longer) and choose "Advance". That should show you if something is muted ot turned down.

Thanks.No,nothing is muted or turned down.

Then only the Greek gods can help you.

He he Thanks.I know!I will take it tomorrow to a pc supporter.Thank you so much anyway.
i followed the windows troubleshooting and it suggests that it might be a problem with the BIOS.

Windows Audio could be stoped.

In this case

Try this:

Right click My Computer chose Manage > Services and Aplication > Services
scroll and find Windows Audio and see if it's started, if not
right click chose proprieties and chose startup type automatic.
Now restart windows.

Thanks,i will try it!

Yeap,i did as instructed and says started.
