C-Media onboard sound is gone?

[Lcarvone]

I have a Asus TUSI-M mobo (SIS630 chipset) which has onboard sound in the form of a C-Media CMI8378 audio chip. It was working just fine until some point today. Windows (98se) can't find it using add new hardware, system file checker shows nothing, two different sets of drivers have been tried (fresh install/uninstalls) with no results, the onboard audio option is enabled in the BIOS, etc. etc. I have tried all I know and it acts as though the chip isn't even there (I checked by the way and it is there

Any suggestions before I bite the bullet and buy a PCI sound card?

Just a thot but if it has a adapter for more than the front channels that got lose or put on backwards the cmedia part can just appear to go away.

On my old soyo dragon I had a card that screwed into the back of the case. I screwed up and put the cable on backwards. No cmedia. Fixed that suddenly windows found it.

Thanks for the reply but no adapter....just basic onboard sound.

Check whether there's a hardware jumper to disable the thing ... it might have fallen off.

Nope...no jumper that I can see or find reference to. Thanks for the suggestion!

Is this C-Media bundled software still there?...might be worth uninstalling anything related to the onboard sound, then reboot and reinstall latest drivers (motherboard manufacturer OR cmedia will have these)

Yes I have tried this. The CD that came with the mobo has a set of drivers and a set of applications associated with the C-Media chip. I have installed/uninstalled these a few times to no avail. One curious this too is that there are also a set of SIS audio drivers (mobo is SIS630 chipset - Asus TUSI-M) in the same folder. I tried to install these after a number of tries with the C-Media set but they (SIS) hung on install at 95% complete.

Thanks for the suggestions!

Try enabling "Reset Data Configuration" in BIOS, this should force windows to re-assign resources.

Cheers

HAHAHAHA!!!! Well I don't have that option in my BIOS so I tried something I should have from the start. I disabled the onboard sound in the BIOS, rebooted, then re-enabled. Voila, sound is back Thanks for the inspiration and help folks!!
