Root cause: PcmPlayer called openPlayer() without audio session config,
so Android defaulted to earpiece-only mode. When the mic was actively
recording, playback was silently suppressed — the agent's TTS audio was
sent successfully over WebSocket but never reached the speaker.
Changes:
1. PcmPlayer (pcm_player.dart):
- Added audio_session package for proper audio session management
- Configure AudioSession with playAndRecord category so mic + speaker
work simultaneously
- Set voiceCommunication usage to enable Android hardware AEC (echo
cancellation) — prevents feedback loops when speaker is active
- defaultToSpeaker routes output to loudspeaker instead of earpiece
- Restored setSpeakerOn() method stub (used by UI toggle)
2. AgentCallPage (agent_call_page.dart):
- Fixed fire-and-forget bug: _pcmPlayer.feed() returns Future but was
called without await, causing interleaved feedUint8FromStream calls
- Added _feedChain serializer to guarantee sequential audio feeding
3. Dependencies:
- Added audio_session package to pubspec.yaml
