Hi all , my first post.. hehe
There are several alternative to creative soundblaster driver , such as
1. EMU driver, from the emu developer themselves for the usage of their APS card

These are just plain drivers, u still need to install creative surround mixer to change the settings and creative play centre to enable cmss.
2. KX project driver

This is a complete set of driver component developed by audio enthusiast..
IMHO , the EMU APS driver is quite better than the KX driver.. but if you like to play a lot with DSP and effect, KX would be a better choice..
Good luck :)
