When I turned off the computer while it was loading Windows 98 SE (and we all know how buggy IT is) and turned it back on again a few seconds later, I found that my sound chip had somehow stopped working and disappeared off the Device Manager. I've done nearly everything I can think of (without spending money): Re-install Windows, turn AC '97 off and then on in the BIOS setup, and even removed and re-installed the Sigmatel drivers (for Intel Chipsets Sigmatel AC '97 audio). Anyone have a solution to this frustrating problem? It would be most appreciated.

Did u try Windowsupdate to see if that can update the drivers for the sound?? Delete the entry in Device Manager first. Does Device Manager show any X's ? or other under this soundcard?? Even with the drivers, you've installed at the mo?

Well its not a good idea to turn it off while Windows is loading. It may have corrupted something. Or try updating the BIOS if there's a later BIOS out for the mobo. Or set the BIOS at its default settings, then reconfigure the BIOS, and save the settings.

Did you reinstall Windows over the top, or format and reinstall.

If it was a format and reinstall then it's not likely to be a software problem.

Try booting in Safe Mode and removing the drivers that way, then go back in and reinstall them.

O.K., I'll try that.
Thanks!

Neither updating or resetting the bios worked and there was no listing for the sound chip in safe mode. An answer to whiskeytangofoxtrot: I re-installed Windows 98 SE over the top, but only after the problem with the sound occurred.

Well I would do a clean install,and DONT install over a previous version.

Meaning I back up my important files, format the hard-drive and install Windows back on? Good idea. I was thinking of doing that, but just wanted to see if there were any alternatives to that, as I already did that last month. At the moment it seems like my only option. Thanks Spacemannz and Whiskeytangofoxtrot for your help.

[Note to other viewers of this topic: I would still like to hear your advice on this problem in case it happens again. Topic is still open]

[another viewer replies] ... Hi Mada , I 'm also really keen to learn more about on-board sound . I can't quite work something out your original post , did you chose to turn off the computer during the installation of 98se ?? Or did it turn itself off during the installation ,or was it a power surge/ young kid pulling plugs / act of God etc etc . IMHO when a win98se install hasn't gone well , I swear loudly , pour another vodka , and put in the bootdisk to start again then reformat, load os , load mobo drivers etc etc . A heaping pile of the 'puters I've put together have SoundBlaster cards in them as I've read this is a better option [ in terms of not straining the CPU ] vs on-board sound - SB cards are easy to find in NZ and offer "OK" performance ... there are new mobos coming out [ Intel] that would seem to offer very tasty on-board audio , it's a changing world ...
Anyway , back to your original post , what happened to cause your problems ? :)

I turned off the computer while it was starting up and loading Windows. I have formatted the hard drive and re-installed Windows 98 SE, but my problem still remains. I've even reset the BIOS settings. Maybe that's where the problem is?
So, my sound is STILL not working X-( and I am really annoyed!

Onboard sound: This is an integrated chip, usually called integrated sound. It can go under numerous prefixes, depending on the manufacturer of the sound chip, such as: Realtek integrated Audio (one of the most common); Sigmatel integrated Audio; and others. Integrated integrated audio usually processes some of its audio data using the CPU, so it can cause a slight performance degradation. Most integrated audio chips can have a sound that is beaten by decent sound cards, but others can be quite good, with features like 6 channel audio.
By the way, I ended up having to buy a new motherboard and CPU, because it seems the sound giving up was only a warning of the things to come, but having a gigahertz CPU is quite nice.
P.S. Only the motherboard gave up. To my knowledge, the CPU runs fine, but is a PIII and not compatible with new motherboards.
