The only reason I see in actions of C-Media: they are lazy to update site. I'm sure they periodicaly release new version of driver for internal use and when question about WHQL arise they send latest available drivers to Microsoft. That's why WindowsUpdate have ver. 643, but C-Media site have ver. …

Most funny thing that driver for Windows XP on windowsupdate.microsoft.com (ver. 643) is newer than on C-Media site (ver. 639). I wrote to C-Media several times but they keep silence.

O.K. Does anybody know why under Win 9X everything is ok but not under Win XP/2000 ???

I trying to find workaround. Port just can be handled correctly, I wonder why things changed in Win XP because in Win 9X everything is almost good, sometimes programs run not so smooth but they do run. Any ideas?
