I have a system that needed a motherboard replaced. That went fine, with one exception, NO Sound. It has been my experience that when a machine has an onboard sound card and you change the motherboard these darn AC97 drivers never work again. Device manager say every thing is ok yet no noise. Does any one have a solution other than Format c:
Remove the sound drivers in device manager and reboot.Quote:

USE the ones included with the mainboard cd if it asks.
IOW choose cancel and then start the mb cd.

That hasn't been my xp.
What OS?
Welcome back to windrivers=which is exactly what you need! :D
The OS is windows ME.
The mobo is a ECS P4VXASD2+.
I removed and then reinstalled. Still no sound.
HOW did you reinstall?Quote:

Also, try speakers that you KNOW work.
Under Sound Devices in Device Mgr what is listed?
I am assuming that the sound worked alright before as well.
Was the mb an exact replacement?
I used the CD, The Mobo is not an exact replacement. And I am using head phones that I know work. :grin:Quote:

While in safe mode, when I click on the setup exe i get an error message that reads "VIA AC97 chipset no found on this system!"Quote:

OK - Win ME and WDM drivers... lets check a few symptoms.
Do the sound drivers install, show up in device manager but when you go to multimedia the playback and record devices are greyed out or not there?
If so, get the 95/98 VXD version of the drivers and install those.
You replaced the motherboard, but it almost sounds like you are using the same drivers as for the old motherboard - that may also be the problem.
If so post the motherboard make and model (and the old one for comparison) - lets go driver hunting for the RIGHT ac97 via drivers!
Edit: Duh - you mentioned the board on the first page - Here are the current drivers on via arena There are the 95/98 drivers - It can be a bit of fiddle getting unsigned drivers to work in ME... but often where ac97 wdms fail, the vxd's triumph.
P. S.
When via ac97 first came out one of the regulars here had to hack the inf to get it to install right.... lots of people downloaded that particular "custom" driver :D
I would love to have this hack. I don't. I have tried the drivers you mention. They didn't work either.Quote:

(the hacked .inf Noo talks about just changes the driver loction to this 98 style .vxd driver as opposed to a WDM (windows driver model) style driver, I think !)
Correct Confus-ed
Now philipmcph, you really need to give us a bit more feed back than it doesn't work. What doesn't, what if any are the errors, what does device manager report in both normal and safe mode? What does the multimedia applet in control panel show?
What was the previous board you had?
Have you looked at the files that have been installed and been through in safe mode and renamed them so windows can't just reinstall the wrong version again?
Have you checked in the registry to see what sound is showing up in the enum keys?
We can move forward as soon as you answer these questions.
To answer the above:Quote:

what does device manager report in both normal and safe mode?: Device manager says everything is OK.
What does the multimedia applet in control panel show? "No Playback Devices" " No Recording Devices".
What was the previous board you had? The previous board is an IBm (Or who ever they use) with an Intel chipset.
Have you checked in the registry to see what sound is showing up in the enum keys? The correct sound card is listed. ( I deleted the enum key and reinstalled all drivers at the time of installation of the motherboard)
OK the fact that you have devices installed correctly in device manager but nothing in the multimedia section tells me this is definitely a WDM driver snafu...
Try this please.
Boot to safe mode. Remove any and ALL devices to do with sound (yes including mp401 but just disable the wave device for a voice modem.) Shutdown, restart and immediately go into bios and disable the onboard sound. Make sure you check all the bios options, the legacy sound is often listed separately to the ac97. Some boards even have a jumper to disable the onboard sound. You need to get the onboard sound completely disabled.
Boot to normal mode see if it detects a new sound card, if it doesn't good. Boot to safe mode and track down and rename the files that the drivers installed.... especially the inf file. Check there are no backup copies sitting in any other directory.
Check the registry enum key for any pci sound devices, if they are there, delete just those devices.
Reboot to normal mode and make sure all is well. Unzip the VXD drivers to a directory that can easily be found - such as c:\sound. Shut down. Re enable the sound device(s) in bios. Boot to normal mode and direct windows to use the c:\sound directory.
Pray. :)
Upon reboot it detects the MP401.Quote:

No i did not take any short cuts.Quote:

By the way, have you carefully checked the bios that both the legacy (DOS) sound is enabled as well as the AC97?
