Right, I had posted my findings with processorOptions but I just tested with postMessage too. Doesn't work there. See https://jsfiddle.net/6ua5o3jk/
Works perfectly fine in chrome.

The SharedArrayBuffer may be getting copied to the other thread and behaving like a normal ArrayBuffer. I verified this when initially setting some values (before sab was transported to the other thread) and later, able to see the same value in the other thread.

(Note in both the test, at step-2 in the attached screenshot if you click anywhere in the browser to activate AudioWorkletProcessor, it may not work directly coz of autoplay issue and then you'll have to reload the browser and check again)
