"OK, I was getting the issue where you run the installer.exe for the soundmax onboard audio and it goes through the whole install and then says "drivers not found" at the end. Here's how I finally fixed it on my 865perl mobo running XP pro:
1) Get the latest drivers. I got mine from the intel site. The installer won't work and you'll get the "drivers not found" error. When you run the install, pay attention to where it unzips the files. The default is C:\program files\intel desktop board audio drivers.
2) Go into device manager and uninstall the non-functioning sound card, multimedia device, etc.
3) Restart. When it tries to auto install new devices it detects, hit cancel. Go to control panel -> Add Hardware. If it says you can only install one device at a time then you have to cancel the other devices it is trying to auto install.
4) When you run the new hardware wizard, select "install from a list or specific location" when prompted.
5) At the next screen choose "Don't search. I will choose the driver to install"
6) At the next screen choose "Sound Video or Game Controllers"
7) When presented with a list of sound devices, Click the "Have Disk" button. When the next prompt comes up, click "Browse."
8) Direct it to the folder where the Intel Desktop Board Audio Drivers were installed. Then to the W2K_XP folder within that folder. The path for me was c:\program files\intel desktop board audio drivers\SMAXWDM/W2K_XP. If you're running Win SE there is an SE folder one step up that I assume would work. Click "Open" button.
9) Select the file smwdmCH0.inf (should be selected by default.) Click Ok. Now the New Hardware wizard should show a bunch of SoundMax stuff to be installed. Click Next and let it finish installing. Restart and for me at least everything was back to normal.
The driver executable was Audio: ADI 1985 [AUD_ALL32_5.12.1.5240_PV2.EXE]
I downloaded it from

I believe the onboard drivers for Soundmax are the same for all motherboards but I might well be wrong so check your Mobo manufacturer's site.
And can I just say, SoundMax. What a piece of junk. Good luck all."
