 ### Bug Fixes
-- Prevent dialog `showModal` from auto-focusing first input ([db777fa](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/db777fa))
+
+- Fix numpy failing to import in the Windows installer — preserve required numpy submodules (`lib`, `linalg`, `ma`, `polynomial`, `fft`, `ctypeslib`, `matrixlib`) during build cleanup ([68614c9](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/68614c9))
+- Fix numpy failing to locate `libopenblas` DLL in the Windows installer — generate `_distributor_init_local.py` at build time and call `os.add_dll_directory()` at runtime ([456eb3a](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/456eb3a))
+- Fix visualizer toggle button not reflecting actual availability after audio device load ([ee51849](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/ee51849))
+- Fix visualizer WebSocket re-subscription firing before availability is confirmed from the API — moved from `connectWebSocket` to `loadAudioDevices` ([ee51849](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/ee51849))

 ### Development / Internal
 
 #### CI/Build
-- Replace `uvicorn[standard]` with explicit Windows-safe extras; avoids uvloop cross-build deadlock ([28293c6](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/28293c6))
-- Move `pystray` into the unified cross-deps resolve so its Pillow matches the core one ([8450040](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/8450040))
-- Hybrid pip-download: single call for cross-platform deps (consistent `pydantic-core`), per-dep loop with `--pre` for Windows-only ([39b3aed](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/39b3aed))
-- Normalize non-PEP440 versions before stamping `pyproject.toml` ([69df9b6](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/69df9b6))
-- Pass `--pre` to `pip download` for winsdk beta wheels ([760c3df](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/760c3df))
-- Revert broken action caching (Gitea cache backend not configured) ([60f287b](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/60f287b))
+- Generate `numpy/_distributor_init_local.py` in Windows build script to fix DLL loading in embedded Python ([456eb3a](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/456eb3a))
+
+#### Other
+- Broaden audio library import errors from `ImportError` to `Exception` and log at `warning` level with error details ([ee51849](https://git.dolgolyov-family.by/alexei.dolgolyov/media-player-server/commit/ee51849))
