I am testing some filter driver on some USB audio firmware. After
enumeration, Win2K could find usbaudio device and usbHID. They are all
listed correctly in device manager, but system will display "sysaudio:
addFilter xxxxxxxxxxxxxxxxxxxxxxxxxxx failed". If I use media player to
play a sound file, it will display "no audio hardware". 



so, anybody knows whey sysaudio will display such error messaage? where
did I commit some thing?
