ST Audio DSP24 WDM drivers for Windows 2000 / XP: v7.1.0928, Beta 5 (10/31/01)
==============================================================================


When should you use this driver?
--------------------------------

This WDM driver can be used together with Windows 98 SE, Me, 2000 and XP. Other
Windows versions (Windows 95 / 98 / NT 4.0) are not supported. We recommend to
use the WDM driver instead of the existing Windows 2000/NT4 drivers if you are
using:

- Windows XP (with any audio software)
- Windows 2000 (if you have problems with the existing drivers)
- Windows 98 SE / Me (if you use Cakewalk SONAR)

If you do not use any of these combinations, please do not use the WDM drivers.


installation
------------

It is important that the existing drivers are completly removed before you
install the WDM drivers for your DSP24. To do this, follow these steps:

- unzip the drivers into a new directory
- goto Control Panel -> Software and uninstall the "Audio DSP24" software
- if you use Windows 98 SE or Me: launch DriverInfo.exe (available on
  www.staudio.com) and select "Uninstall Driver"
- if you use Windows 2000 or XP: goto Control Panel -> System -> Hardware -> 
  Device Manager and delete the entry of the DSP24 card, do not reboot if
  Windows asks you to do so
- if you use Windows 2000 or XP: goto the directory WINNT\INF and check all
  files with an OEMx.INF name. Delete any of the files that contain "Hoontech"
  or "ST Audio" (open them to check, then delete them if needed)
- shutdown and reboot the system (installation will not work properly unless
  you reboot the system)

You can install the new WDM driver now. Windows will detect the DSP24 card as
a new hardware component. Make sure to give Windows the directory with the WDM
driver when it asks for driver information.

After the driver is installed, the new updated version of the applications need
to be installed. Existing applications (External Links, External Mixer) are not
compatible with the new WDM driver. To install the apps:

- launch AudioDSP24Api(WDM 2001-10-31).exe from the driver download and follow
  the instructions on screen
- now reboot

The installation of the driver is finished now.


general information
-------------------

The DSP24 WDM Driver is a new WDM driver that supports all basic functions as 
WaveOut, Recording, MIDI, etc. as the existing drivers. Also the applications
have the same user interface and functions as previously.
 
Differences to the existing Windows NT4/2000 drivers:
 
1) Multi-Card support (support for up to 4 cards)
2) H/W and Box/Routing related settings are set by the driver now, this means
   that External Links no longer must be in the StartUp group (we still
   recommend this)
3) You can use DirectSound output on any output device because they're WDM.
4) Stability is improved.
 

Functions that are not supported in this driver but will be added:
 
1) GSIF and Multi-Client (MME/GSIF/ASIO support simultaneous)
   GigaStudio for Windows 2000 / XP is not available to the public yet. We
   are working to add support for this software under Windows 2000 / XP
   already however
2) AC-3 output (S/PDIF format support)
3) Direct3D support (4 channel out, Output1/2/3/4)
