After the Stereo Out attribute of the track configured with the Panner plug-in is set to no bus, we find that the PCM sampling point data sent by Nuendo 11 is later than that sent before. As a result, the data rendered by the Render cannot be obtained in Return plug-in.
Is the data delay mechanism of the Panner plug-in affected after the Stereo Out attribute of the track is set to No Bus?
If I correctly understand your question, then I would say lookup the documentation of IAudioPresentationLatency. If you implement this in your panner plug-in you can always know how long it takes until the audio is coming out of the speakers.
