Typically, an MS-DOS-based multimedia application writes directly to
the I/O ports of an installed sound adapter to perform audio
functions. To support system security in Windows NT, an application
cannot write directly to the hardware ports, it must write to a VDD
(virtual device driver) that simulates the sound adapter. Currently,
Windows NT does not include any VDDs for sound adapters; multimedia
applications that perform direct I/O are not supported.
Microsoft will post new information here in the Microsoft Knowledge
Base as these modules are available to install in Windows NT.
