Subject: [wdmaudiodev] Can I use IAudioProcessingObject::Reset to retrigger
format negotiation without stopping previously-ongoing audio processing?
Hello wdmaudiodev people
I am writing an APO whose input format compatibilities may change
mid-audio-process, (when the user changes a certain property, which can happen
at any time).
So essentially when the User makes this property change, I'd like to restart
the whole format negotiation process, preferably without stopping audio
playback (I can accept the inevitable audio "click/pop" that will result).
my friend here? As far as I can tell, this will do what I need, although it's
not clear if Windows will restart audio playback (if it was ongoing) after the
Reset call and all the other calls that it precipitates.
(Btw I'm using "old-style" APO, as I need Win7 compatility).
