Nothing has changed from a technology stand point. Echo has always done all the engineering support for these cards, and will continue to do so, as evident with their latest release of v5.0 - the long awaited multiclient drivers.
PLEASE be aware of two issues if you are using these new drivers:
1. They only work with v1.6 or later of GS or GSLE.
2. You MUST disable the DirectSound compatibility before GS or GSLE will work with these drivers. Do this by going to the driver\'s property page in the Device Manager and disabling. Unfortunately, these drivers get installed with this feature on, and you will need to turn it off for GS to work.
