Im running Win7 x64 with the Audigy 2 ZS, all the drivers from creative install fine including the game port. http://support.creative.com/Products/ProductDetails.aspx?catID=1&subCatID=205&prodID=4915&prodName=Audigy%202%20ZS&subCatName=Audigy&CatName=Sound+Blaster&VARSET=prodfaq:PRODFAQ_4915,VARSET=CategoryID:1
The only error that i seem to get is when i click on the speaker icon on the mixer to bring up the speaker properties which reads:
" Windows has detected that the audio enhancement for the following device is causing problems:
Speakers(Creative SB Audigy 2 ZS (WDM))
Would you like to disable driver enhancements for this device? Yes/No "
I have not gotten any problems with selecting "No" so far on mine.
