[Locked] Audio problems

I am having trouble with my Dell notebook. For some odd reason, it stopped playing all sounds the other day. I tried headphones but they didnt work either.

OS: Windows XP Professional
Possessor: Intel Centrino
Uses SigmaTel Audio

If you need more info, just say so and I'll put up what you need

Thanks in advance FAKKU!

Hmmm...that's pretty odd. Did you install anything before it stopped working? Windows update, anything? Windows has been known to update your drivers which in turn causes them to stop working...

First off you should probably try reinstalling the driver, I'm sure you can find the driver off the Dell website (I don't use Dell) if you can't find that try googling for SigmaTel Audio driver.

This might seem a bit obvious but did you accidently mute the audio? There's usually a hotkey that mutes the sound with notebooks, you might have accidently pressed it.

I was able to fix this by updating my drivers. Still, It makes me wonder what caused this preoblem.

Thanks.

Glad to help.
Improper shutdown can cause drivers to malfunction. Windows update can do that too. Premature ending of some processes can cause drive to malfunction too, in rare cases (linked to improper shutdown I guess).
