No Sound after Motherboard Upgrade

[ozrica]

I have just upgraded four machines with new Motherboards, CPU and Memory.
Two of the systems use an Asus A7N8X-X (nForce2 400 - nForce Audio Codec) and the other two use an Asus P4S8X-X (SIS648 - SoundMax Digital Audio System).

I am experiencing the same problem as people on this thread:

but I am using Windows 98SE.

In device manager the driver is installed and working OK but in Multimedia Properties under Control Panel there are 'No Playback Devices' available (the selection is greyed out).

I have not wiped the hard drives as this will take too long.

I have also tried the latest drivers from Asus.

Any idea how to fix this?

No yer not !

The thread you refer to is about the windows audio service being left off in xp because plug & play couldn't or didn't think it could start it - no such service available in 98 as that doesn't use the wdm (windows driver model) - but hell we don't care about xp just now .. this is in 98 !

So that's me done with 'counter- confusing' !

Here I'd just say add any chipset patches, then do the 'enum trick' ..

'Destructions' here (pretty good too - I reckon )

Cheers Confus-ed.

I'll give it a go and let you know how I get on.

There's also the good ole replace the win.ini file with a recent backup if you have one trick.

OK. I ran the process and all worked exactly as stated. Unfortunately I'm still left with the same problem!

Any other ideas?

This is the old wdm versus vxd drivers. Trouble is you are stuck with only wdm drivers. So, my suggestion would be install the motherboard drivers, update 98se using windows update.

Boot to safe mode, uninstall the sound drivers from add/remove programs, remove the devices from device manager. Shut down Go into bios, disable all sound devices - ac97, and any attendant legacy features such as mpu401, game port etc.

Start up normally. Reinstall mobo drivers, check for any more windows updates. Shut down, enable sound in bios
boot to normal mode and try again.

The all googling one beat me to the punch again ... that's pretty much the answer I had just written, but not pressed return on, while I went to read a pm from her !

I'll just repeat 'chipset patches' !!! & say whatever the onboard audio may be (I'd googled one, which was;- Realtek® ALC650 audio CODEC) try what Noo says .. this can help with irqs & resources - windows gives preference to isa cards, then pci, then agp - onboard sound is often wired via the isa bus (whether you think you've got one or not, you will have !) so this 'trick' helps too ..

Thanks a lot to both of you.

I'll let you know what happens.
