<h2><span style='font-family:Verdana'>Audio GFX Filter Sample<o:p></o:p></span></h2>
<p><span style='font-size:10.0pt;font-family:Arial;color:red'>[This is
preliminary documentation and subject to change.]</span><span style='font-size:
10.0pt;font-family:Verdana'><o:p></o:p></span></p>
<h3><span style='font-family:Verdana'>SUMMARY<o:p></o:p></span></h3>
<p><span style='font-size:10.0pt;font-family:Verdana'>This sample driver demonstrates
the basics of writing an audio GFX filter. On Microsoft Windows XP, only <span
class=SpellE>autoload</span> <span class=SpellE>GFXes</span> are allowed. That
means that a GFX can only be applied to specific PnP IDs of USB audio devices.
The sample GFX is therefore tied to the Microsoft DSS 80 USB speakers. You can
modify the INF file and replace the PnP ID with the PnP ID of your USB audio
device to load the GFX on your device.<o:p></o:p></span></p>
<h3><span style='font-family:Verdana'>BUILDING THE SAMPLE<o:p></o:p></span></h3>
<p><span style='font-size:10.0pt;font-family:Verdana'>To build this sample,
enter the free or checked Windows XP build environment and run <b>build</b>
from the parent directory, rather than this subdirectory. This will also
compile the GFX property DLL which allows the user to change the properties of
your GFX.<o:p></o:p></span></p>
<p><span style='font-size:10.0pt;font-family:Verdana'>The INF file named ‘<span
class=SpellE>gfxswap.inf</span>’ included in the parent directory can be used
to install the sample driver together with the GFX property DLL after it has
been built. Simply copy the INF and this binary and the GFX property sample
binary to a floppy disk and right click the INF file and choose ‘Install’ on
your test machine. Please also refer to the ‘readme.htm’ file in the parent
directory.<o:p></o:p></span></p>
<p><span style='font-size:10.0pt;font-family:Verdana'>Once the driver has been
installed with the INF, the driver may be updated by copying the binary into
%SystemRoot%\System32\Drivers on the target machine and rebooting to test the
new driver, provided that there are no INF changes.<o:p></o:p></span></p>
