That's an ingenious way, thank you.
We divided the sound acquisition, filtering and transmission into 3 simultaneous while loops connected with buffers. It didn't solve the issue, but in the process we changed the Resample components from continuous to "1-shot" and that was evidently the issue. Somehow having this continuous while switching music tracks or disrupting the wave stream shortly would cause issues further down the pipeline in the Transmitter component.
So solved overall while achieving removal of local variables, fixing references and utilizing many more shift registers. Thanks!
