Are you playing avisynth script? Currently the waveform can update during playback only when using caching input driver.
This is because audio must be read concurrently on two threads, and most sources do not support this. I was thinking on possible solution, best I can imagine is to buffer a window long enough to satisfy both ends. This feels surprisingly complex.
