 - **AudioWorklet**: Fix stale output when the data callback grows Wasm memory.
 - **JACK**: Channel enumeration is capped at the physical system port count again.
 - **WASAPI**: Device enumeration no longer panics if the COM enumerator fails to initialize.
+- **WASAPI**: Revert "Default device changes no longer report `DeviceChanged`" as it was misinformed.
+  Default device streams **do** reroute automatically.
