User report at +66: capture (mic -> remote) is clean, but local playback (remote -> speaker) is 'broken and poor', particularly for human voice. Musicbot audio (loud, near-continuous) plays correctly; human voice (peaks ~-6 dB, average ~-40 dB, classic 20 dB peak-to-average ratio) sounds gated out so most inter- phoneme content is unintelligible. Diagnostic at +66 (render callback peak sampling every 100 callbacks during a 60-second talker session) showed peak_stereo values in the 0.005-0.01 range with occasional 0.13-0.49 spikes \u2014 i.e. the signal is REAL and reaching the device, but VPIO's output-side voice processing chain is gating the average-level content. Root cause: AVAudioSession mode .default + VPIO is a mismatched pairing. Under .default mode the VPIO unit's internal AGC/NS thresholds are tuned wrong for telephony-style speech and treat quiet inter-phoneme content as noise to gate out. Fix: switch back to mode .voiceChat which is Apple's documented pair for VoiceProcessingIO. WebRTC's reference iOS audio device manager (chromium googlesource voice_processing_audio_unit.mm) also uses this pair. VPIO under .voiceChat tunes its processing chain for speech and passes quiet content through cleanly. The original 'speaker/receiver toggle is silent under .voiceChat' bug was caused by cpal's RemoteIO unit binding to a stale physical transducer at construction time, not by .voiceChat itself. After migrating to VPIO at commits 1-4 (af686cathroughe7c3ffa) the route binding is correct under either mode because VPIO natively re-binds on overrideOutputAudioPort \u2014 it IS the canonical voice unit. So .default lost its only benefit and we revert to the Apple-documented pairing. Category options unchanged: .allowBluetoothHFP + .allowBluetoothA2DP \u2014 BT headsets still permitted in both directions regardless of mode. Build counter 66 -> 67.
