This is the Crystal Sound Fusion drivers needed for the eMachines eOne 433. Please make sure to download acs51.zip and unzip both these files to a single directory to install. Since eMachines offers no drivers, poor support and has no links to the eOne what-so-ever on their web page, I had to search all over the web to find these drivers. I am putting them here in the hopes you won't have to search as hard or as long as I did to locate them. Boycott eMachines!
