All,
I'm working on installing the sample APOs for Vista using .inf files.
I find that if I install e.g. the "swap" sample, which has a custom
property page, that I get an enhancements tab in the audio control
dialogs; this allows me to enable the effects, and indeed I can debug
the source code for the sample, which is being invoked by audiodg.exe.
However, if I install the spkrfill example, which does not have a
custom property page, I get only the default" "enhancements" tab, which
has a tic box named "Disable all enhancements". There does not appear
to be a special entry in the enhancements for the sample, though the
stock Vista enhancements are present. If I untic the "disable", it
still does not appear that the sample code is called (audiodg.exe does
not invoke the .dll, though it appears to have installed correctly (
the .dll is present in windows\system32, and the relevant registry keys
appear to have been made correctly)).
sysfx.doc says that there is a default PKEY_Endpoint_Disable_SysFx
setting, which is by default disabled. I get the impression that this
global setting applies to an IHV APO which does not have a custom
property page installed, though I'm not positive on this point.
Should unticing "Disable all enhancements" cause the IHV APO (the
sample) to be invoked? if not, must I add some kind of control,
registry entry, etc. to enable/disable it separately? If this is not
the case, what might cause the spkrfill sample not to be invoked on the
same hardware for which the swap sample appears to run fine?
Many thanks,
Bill
