Diagnosed by comparing against TeamTalk5 (Client/iTeamTalk), which achieves stereo mic + A2DP output. Five fixes: 1. configureStereoCapture now calls setPreferredInput + setInputDataSource (mirroring TeamTalk5's SoundDevicesModel). Previously omitted based on incorrect diagnosis that setPreferredInput collapsed A2DP — the real culprit was setPreferredInputNumberOfChannels(2), which neither project uses. 2. New C ABI: vc_audio_restart (full stop + re-init, unlike suspend/resume which only stop/start). Swift wrapper added. The withAudioSuspend wrapper that used it was removed after on-device testing showed it killed all audio (including VoiceOver) when switching presets — the core's set_capture_channels handles engine restart internally. 3. Bluetooth options: Voice Chat preset now includes BOTH .allowBluetoothHFP AND .allowBluetoothA2DP (matching TeamTalk5's UtilSound.swift:228). Previously HFP-only blocked A2DP headphones. 4. Capture channels now reset when switching stereo→mono via selectCaptureChannels/applyPreset. AudioSessionManager tracks activeMicStreamId (set by SessionState on join/leave voice). 5. Docs synced: voice.md, tech-stack.md, architecture.md, PROGRESS.md. Removed stale setPreferredInputNumberOfChannels(2) references. Verified: ctest --preset dev 21/21 green, iOS client builds. Stereo mic + A2DP output still needs on-device debugging — the core recipe is correct but iOS 26 route behavior requires hands-on testing with a debugger.
VoiceCat
Self-hosted, native voice & text chat in the spirit of classic TeamSpeak / Mumble —
channel-based voice, channel + private text, one server you run yourself. Plain TCP
(control) and UDP (media), no WebRTC. Encrypted by default. A shared C++ core
(libvoicecat) drives native clients (Swift on macOS/iOS, C# on Windows) and the server.
Status: Design complete in
docs/. M1–M5 are implemented — real TLS control plane, encrypted UDP voice (Opus), multi-stream, TOFU identity pinning, channel tree, permissions, moderation, disconnect/keepalive/reaper. Windows WinForms C# client shipped (M4). macOS/iOS Swift client is next. SeePROGRESS.mdanddocs/roadmap.md.

Build
The default development preset is dev — it builds everything (server + tools + tests)
with real vcpkg deps. It works on Windows, Linux, and macOS (vcpkg triplet auto-resolved).
# one-time vcpkg setup:
git clone https://github.com/microsoft/vcpkg && ./vcpkg/bootstrap-vcpkg.sh # .bat on Windows
export VCPKG_ROOT=/path/to/vcpkg # Linux/macOS; or $env:VCPKG_ROOT on PowerShell
# configure + build + test:
cmake --preset dev
cmake --build --preset dev
ctest --preset dev # 21 behavior tests
Artifacts land in build/dev/bin/ (voicecat-server, vccli, voicecat-admin).
The skeleton preset (no vcpkg deps, stubs only) is a fast smoke check that needs no
third-party libraries:
cmake --preset skeleton && cmake --build --preset skeleton && ctest --preset skeleton
See docs/building.md for the full preset matrix (including release,
server-release, windows-client, and Apple platform scaffolding).
