Win2000 and NT4 audio drivers

Hello everybody!

I have the following problem. I have written ( a long time ago ) an NT4
driver for my GUS audio card. Under NT4 it worked perfectly ( or at least
good :)). But when I tried to install it on Win2000 it didn’t work. Although
it starts without a fail, creates WaveOut0 symlink etc, Win2000 multimedia
console doesn’t indicates that there is a audio device present. Any ideas ?
Maybe I should change something in my driver to conform Win2000 requirements ?

Please, help.

With respect, Max.
