Hello,
Sorry for barging in like this, but I see there is some misunderstanding regarding the
AC97 ASIO driver I've released and I'm curious if this is a fault on my part by not providing enough info on my web page.
Please let me know if that is the case.

Anyway;
Since the arrival of Kernel Streamers like Asio4All we now have two types of ASIO drivers;
1. Native (like the ones that ship with pro-audio cards)
2. Generic (Kernel Streamers like Asio4All)

The AC97 ASIO driver I released is Native.
It is the same type of driver like the ones that ship with pro-audio cards.
Namely a driver consisting of a hardware specific WDM Kernel driver part and a native ASIO DLL part.

Kernel streamers like Asio4All do not provide a hardware specific WDM Kernel driver part. Just a generic ASIO DLL that "rides on top" of the already installed Vendor WDM Kernel driver.

Pros/Cons
Native ASIO drivers are written specifically for their hardware and as such can/should provide better ASIO performance but of course only work on the hardware they were written for.

The Generic ASIO Kernel Streamers work on top of almost any WDM audio driver, but as such can only be as good as the driver they "ride on".
Not seldom Kernel Streamers like Asio4All even perform better then the native ASIO
drivers shipped with certain cards.
