Ray-Ban Meta glasses pair to the Mac as a Bluetooth HFP microphone; the desktop app captured only from the system-default input with no way to pick a device or see which one is live. Now: - Settings -> Transcription gains a Microphone card: System Default or any input device, enumerated via the same CoreAudio HAL walk as findBuiltInMicDeviceID; persisted by device UID (IDs aren't stable across reconnects) and resolved at capture start via the existing AudioCaptureService(overrideDeviceID:) path. - Meta glasses are detected by precise product-name match (Ray-Ban / Oakley Meta — never generic 'glass') and labeled, with the HFP voice-quality tradeoff stated in plain language. - The Dashboard Listening button shows 'Ray-Ban Meta' while the glasses are the active capture source (recordingInputDeviceName already feeds input_device_name on memories, so provenance lands server-side too). - Silent-mic watchdog behavior is unchanged: a dead Bluetooth mic still falls back to the built-in mic so capture never silently records nothing. - Neutral styling (no purple) per design rules. Verified: xcrun swift build -c debug --package-path Desktop — zero errors (after merging upstream b4370fc, which fixes a pre-existing AgentBridge break at this branch's original base). On-device run via named bundle next.
On-hardware finding: Ray-Ban Meta glasses advertise a Bluetooth codename (observed: 'EL AI 000F'), not a Meta product name, so product-name matching alone can't identify them. When the user has explicitly chosen a microphone, show that device's real name on the Listening button (still 'Ray-Ban Meta' when the name does match a Meta product). Verified on hardware: glasses selected in the picker captured live audio end-to-end to transcript.
With the Settings microphone picker pinning transcription capture to a Bluetooth mic (e.g. Ray-Ban Meta glasses), push-to-talk could open a second CoreAudio IOProc against the same device — or join its A2DP-HFP profile flap — racing both captures' stream-format reconfiguration. PTT's existing guard only considered Bluetooth output. - AudioCaptureService gains a process-wide active-capture registry (register on successful start/reconfigure, unregister on stop). - preferredPTTInputOverrideDeviceID() now also yields to the built-in mic when the would-be input is held by another capture, or is Bluetooth while any capture is live — mirroring the existing isDefaultOutputBluetooth guard's philosophy. Verified: xcrun swift build — zero errors; behavior check on hardware (glasses Listening + chat shortcut concurrently) is the follow-up step.

Pull request overview
Adds a user-selectable microphone input for macOS transcription (including Ray-Ban Meta glasses), surfaces the live capture source in the Listening UI, and introduces a process-wide “active capture” registry to reduce push-to-talk (PTT) contention with ongoing transcription capture.
Changes:
- Add a Settings → Transcription “Microphone” card to pick System Default vs a specific input device (persisted by device UID).
- Show the selected/live capture source name on the Listening button (with a “Ray-Ban Meta” label when name-matched).
- Add an active-capture registry in
AudioCaptureServiceand extend PTT mic override logic to yield to the built-in mic under contention/Bluetooth conditions.

Confidence score: 2/5
- In
desktop/macos/Desktop/Sources/AudioCaptureService.swift, the active-capture registry can be cleared before asyncAudioDeviceStop/destroy finishes, and it may never be cleared if an instance deallocates while still capturing; that can let a new PTT/capture start against a device still shutting down or leave stale ownership behind. Keep the registry entry until stop/destroy completion and ensure deinit/teardown always unregisters before merging. - In
desktop/macos/Desktop/Sources/AudioCaptureService.swift(reconfigureAfterChangepath), contention checks can keep using the old device ID after a live capture switches inputs, which can incorrectly block or allow capture on the wrong microphone. UpdateactiveCaptureswithnewDeviceIDafter a successful restart to keep PTT arbitration accurate. - In
desktop/macos/Desktop/Sources/MainWindow/Pages/Settings/Sections/MicrophonePickerCard.swift, callinglistInputDevices()on the main actor from.onAppearrisks UI stalls during CoreAudio/HAL transitions (for example, Bluetooth discovery). Run device enumeration off the main thread and marshal results back to the UI. - In
desktop/macos/Desktop/Sources/MainWindow/Pages/Settings/Sections/MicrophonePickerCard.swiftanddesktop/macos/Desktop/Sources/AudioCaptureService.swift, the device list is only loaded once and the new preference key bypassesDefaultsKey, so users can miss newly connected mics and future key drift can desync reads/writes. Add a device-change refresh path and route the new key throughDefaultsKeybefore merge.

Thanks for the focused desktop microphone-picker work here — the shape makes sense for Omi’s desktop transcription/smart-glasses use case, especially persisting CoreAudio UIDs rather than device IDs and reusing the explicit AudioCaptureService(overrideDeviceID:) path.
I’m going to hold this before merge for one concrete reason: the required Desktop Swift Build & Tests check is failing in the e2e flow coverage gate, not in compilation. The failing job reports these changed Swift files still need e2e flow coverage entries:
desktop/macos/Desktop/Sources/AppState/AppState+Transcription.swiftdesktop/macos/Desktop/Sources/FloatingControlBar/PushToTalkManager.swiftdesktop/macos/Desktop/Sources/MainWindow/Pages/Settings/Sections/MicrophonePickerCard.swiftdesktop/macos/Desktop/Sources/MainWindow/Pages/Settings/Sections/SettingsContentView+Transcription.swift
Please add/extend the relevant desktop/macos/e2e/flows/*.yaml coverage for the Settings → Transcription microphone picker and the PTT/mic-contention path (or otherwise satisfy the strict coverage checker), then rerun the desktop check.
A couple of maintainer notes for the human pass:
- Product fit looks qualitatively reasonable: a desktop microphone picker and explicit Ray-Ban Meta capture indication are aligned with Omi’s smart-glasses/transcription surface.
- This is still a nontrivial feature PR touching capture routing, Bluetooth/HFP behavior, dashboard UX, and PTT contention, so it should get human maintainer review after CI is green rather than an automated approval.
- I did not find an agent-instruction or AI-reviewer behavior change in this PR.
Once the coverage gate is fixed, I’d expect this to be a good candidate for a final desktop maintainer review with hardware/UX confirmation.

beginTurn() refreshes the voice seed asynchronously and then calls reconnectWarmSessionIfSeedStale(). When the seed fetch is slow (~5s observed), the check lands after a short turn has already committed and teardownSession() destroys the session the turn is awaiting its reply on — the reply silently never arrives. Observed on hardware (glasses Listening + chat shortcut): 'turn committed' at t+0ms, 'voice seed changed — reconnecting warm session' at t+13ms, no reply. Guard the reconnect on inputTurnInProgress/responding and defer to the next turn's check. Verified: xcrun swift build zero errors; hardware re-test of Listening+PTT is the follow-up.

Opening a CoreAudio input can take seconds under load (observed ~5s with
the capture pipeline spinning up, Bluetooth contention, or cold audiomxd
state). PTT cold-started a new AudioCaptureService every press, so short
turns heard nothing ('discarding hub turn — audio 0.00s') and even
successfully opened devices were thrown away when the open completed after
the turn ended.
- Turn end now PARKS the running capture (running-but-dropped via a
lock-guarded lease the frame closures consult per chunk) for 120s instead
of destroying it; the next press adopts it and hears audio immediately.
- Late-completing opens are parked warm instead of stopped.
- Frame/silent-mic closures route by lease (generation + batchMode), so a
parked capture never leaks frames and adoption needs no closure rebinding
on the live IOProc thread.
- Device-failure paths (silent-mic fallback, CoreAudio rebuild) discard
rather than park, so a broken device is never kept warm.
Verified: xcrun swift build zero errors; hardware retest (Capture ON +
Listening on glasses + rapid PTT turns incl. barge-in) is the follow-up.

Because the registry is intended to prevent exactly this contention, consider registering before `AudioDeviceCreateIOProcIDWithBlock`/`AudioDeviceStart` and removing the registration if creation or start fails.</comment>

There was a problem hiding this comment.
P3: The assertion on line 101 checks a log message string that a developer could reword without changing any behavior — for example, changing deferred voice seed reconnect after turn completion to deferring voice seed reconnect until the current turn ends would break the test despite identical behavior. The other three assertions in this test (reconnectWarmSessionWhenTurnCompletes = true, private func reconnectDeferredWarmSessionIfNeeded(), and call-count ≥ 3) already cover the structural properties you're verifying. Consider removing this log-message assertion to avoid brittle test maintenance.

What
findBuiltInMicDeviceID, persisted by device UID (IDs aren't stable across reconnects), applied through the existingAudioCaptureService(overrideDeviceID:)path. Neutral styling; changelog fragments included.AudioCaptureServicegains a process-wide active-capture registry, andpreferredPTTInputOverrideDeviceID()now yields to the built-in mic when the would-be input is held by another capture or is Bluetooth while any capture runs — extending the existingisDefaultOutputBluetooth()guard's philosophy.Why
Ray-Ban Meta glasses pair to a Mac as a Bluetooth HFP microphone, but the app only captured from the system-default input with no picker and no visible indication of the live source. Companion to the mobile-side #9178.
