--- Comment #5 from Chris Dumez <cdumez at apple.com> ---
Ok, so when constructing a SerializedScriptValue, the default SerializationContext  is SerializationContext::Default and it is likely what we end up using for sending the options to the AudioWorklet. However, looking at our implementation, SharedArrayBuffer are only serialized as shared when SerializationContext is SerializationContext::WorkerPostMessage. I am not sure why that is (Yusuke, do you know?).

In anyway, I bet that using SerializationContext::WorkerPostMessage as serialization context for AudioWorklet will work. I'll test.
