CMI8738/C3DX 5.12.1.643 (v0643) 11/27/02
XP 2000 ME 98SE Drivers and Software

THIS IS NOT AN OFFICIAL RELEASE OF THE STAND-ALONE INSTALLER VERSION 0643
- Apparently C-Media did not release any of the new drivers or volume control
software after v0639, but did provide them to Microsoft Windows Update, which
unfortunately doesn't install correctly or allow to configure the 6 channel
outputs (go figure, Microsoft).
THIS IS HOW EVER THE OFFICIAL v0643 DRIVERS AND SOFTWARE PACKAGED WITH AN
OFFICIAL (v0639) INSTALLER, WHICH SEEMS TO WORKS PERFECTLY.
- Unlike the MS 0643 build only available through windows update, this one
installs the volume control correctly and allows for setting controls (the
only way to change the 2/4/6 channel outputs and other settings).
If you did install the MS versions of the drivers, uninstall them first
through Add/Remove Programs, it should be "PCI Audio Driver". Restart, and
then install with the provided setup program. If windows try’s to auto
install the drivers upon restart cancel out of it.
Everything below here is from the original 0639 install readme.txt
