[12/19/97] - Interesting News for OS/2 Developers 

IBM is really working on driver problems for OS/2 in a big way, in
addition to GRADD (for easier display driver development) and I2O (os
independent drivers) there seems to be an OO (object-oriented) Audio
Driver for OS/2.

"Introduction 

The object-oriented (OO) OS/2 Audio Device Driver Sample is provided to
make it much easier for you to develop an OS/2 audio driver. It is
intended to serve as a roadmap for developing an OS/2 audio device
driver." 

...

"Some of the highlights this sample includes are: 

--Full-duplex capability. 
--Real-time MIDI operation that runs at task time context hooks. 
--Wave, Wavetable, and FM synthesis technologies are clearly encapsulated
into distinct modules in the new sample. They can be mixed and matched
as needed. 
--This sample is coded with the Watcom 10.6 compiler. Most of the
existing samples (including the PAS16) are written for a version
of the Microsoft "C" compiler which is no longer available in the
marketplace.
--This sample exploits the OS/2 Resource Manager for identification
and allocation of I/O resources for ISA Plug and Play adapters."

     For more information on this see the Object-Oriented Audio Device
Driver
Sample:

     Also there are some new samples available in the Developer
Connection Device Driver Kit
(http://service.software.ibm.com/ddk/whatsnew.html) for those
interested. The new samples include: Sample Audio Mixer Application and
a sample MPEG Playback application.
