Apply PR #262's device-buffer fix for clicks caused by audio underruns.
Reconfigure on both output-device and hardware sample-rate changes, respect
the device's frame range, and read back the actual buffer size. Avoid
rewriting unchanged sizes when buffer changes notify the format listener.
Remove listeners before teardown, including failed initialization, so they
cannot configure a device that the AudioUnit has already released.
Add hardware-independent regression coverage for switching, rate changes,
scope filtering, limits, synchronous notifications, diagnostic overrides,
absent devices, and listener cleanup. Record the original gameplay evidence
and the additional silent Core Audio validation in the audio reference.
Validation: full host tests, Mac host build, docs checks, and the iOS source
compile check (178 files) passed. Silent USB/speaker switching and speaker
rates of 44.1/96/48 kHz verified 221/480/240 frames. HDMI switching and
gameplay listening after these listener changes remain unvalidated.

GetVibrationDeviceHandles used routed haptics availability to decide whether
handles existed. Games that cache this answer at startup could retain an empty
answer after a controller connected. Return handles for a connected npad style
when rumble is enabled and an output sink is installed; check routed outputs
when values are sent, keeping the existing permission and lifecycle behavior.
Include the PR's rumble diagnostics, count unroutable values individually in
mixed batches, and protect aggregate counters across game threads. Correct the
code comment to describe Unicorn Overlord's observed empty handles and zero
values without claiming restored physical rumble.
Add regressions for cached startup handles delivering a nonzero value after
routing, diagnostic totals and concurrent sends. Include HID in the existing
ThreadSanitizer target and record the mechanism in the service reference.
Checked with GAME=010069401ADB8000: full host suite, 73 HID checks, audio and HID
ThreadSanitizer checks, docs checks, Mac host build, and iOS compilation
(133 files). Physical rumble and iOS runtime remain untested. Broader tool
validation is incomplete because Capstone is missing and iconutil failed.
