WDM Audio Sample Code Notes
|
||
|
|
|
||
|
|
------------------------------------------------------------------------------
|
||
|
|
|
||
|
|
This directory contains several samples of WDM audio drivers and miniports.
|
||
|
|
Each of these is contained within a subdirectory as indicated below:
|
||
|
|
|
||
|
|
STDUNK:
|
||
|
|
|
||
|
|
This directory contains source code for basic standard unknown support that
|
||
|
|
linked into the other WDM audio samples. This facilitates the use of COM-like
|
||
|
|
constructs in the WDM audio drivers.
|
||
|
|
|
||
|
|
UART:
|
||
|
|
|
||
|
|
This directory contains source for a WDM audio miniport to driver a UART type
|
||
|
|
device. This sample shows some of the basics of how one might go about constructing
|
||
|
|
WDM audio miniport. Note that this miniport sample is only a piece of a complete
|
||
|
|
driver and simply compiles to a library that may be linked with additional code
|
||
|
|
to form a complete driver.
|
||
|
|
|
||
|
|
FMSYNTH:
|
||
|
|
|
||
|
|
The fmsynth directory contains source code for a miniport for FM synthesizer
|
||
|
|
devices. This sample shows some of the miniport basics and, as with the UART
|
||
|
|
miniport sample, can serve as a starting point for customization if the system
|
||
|
|
supplied miniports for UART and FMSYNTH do not meet your needs. This miniport
|
||
|
|
is not a complete driver and the library built from this sample needs to be linked
|
||
|
|
with additional code to form a complete driver.
|
||
|
|
|
||
|
|
MPU401:
|
||
|
|
|
||
|
|
The mpu401 directory contains sample code for a 'stand-alone' MPU401 driver.
|
||
|
|
This driver, when combined with either the system supplied UART miniport or the
|
||
|
|
UART miniport sample from this DDK, forms a complete MPU401 WDM audio driver.
|
||
|
|
The driver is currently setup to link with the DDK UART miniport sample driver.
|
||
|
|
Simple changes can be made to the 'sources' file within the mpu401 directory to
|
||
|
|
enable the driver to utilize the system supplied UART miniport.
|
||
|
|
|
||
|
|
SB16:
|
||
|
|
|
||
|
|
This directory contains a complete WDM audio sample driver for SB16 type devices.
|
||
|
|
The driver shows examples of how to utilize several miniport drivers to form a
|
||
|
|
complete driver solution that includes wave audio, mixer topology support, et cetera.
|
||
|
|
The driver can be installed using the INF provided in the SB16 directory.
|
||
|
|
|
||
|

|
|

|
|
Build Notes:
|
||
|
|
|
||
|
|
Several of the sample drivers rely on linking to stdunk.lib. This lib is
|
||
|
|
generated from the code within the stdunk subdirectory. So, at least initially,
|
||
|
|
it is probably best to build from the ntddk\src\audio directory to ensure that
|
||
|
|
all of the samples and libs are built and are current.
|
||
|
|
|
||
|
|
Install Notes:
|
||
|
|
|
||
|
|
The INF included in the ntddk\src\audio\sb16 directory (mssb16.inf) can
|
||
|
|
be used to install the SB16 sample driver after it has been built. Simply copy the
|
||
|
|
INF and the driver binary to a floppy disk. You can then install from that
|
||
|
|
floppy. Once the driver has been installed successfully with the INF, you
|
||
|
|
can simply drop updated driver binaries into \windows\system32\drivers
|
||
|
|
on the target machine and reboot to test the new driver (provided that you
|
||
|
|
are not also making INF changes).
