Thanks — I hear you: you’re a presenter (no VPN) on an up‑to‑date OS/browser and you’re seeing packet loss on your microphone track. Let’s walk through focused checks and quick fixes. First checks (quick, do these now) • Run a connection test: use LiveKit’s ConnectionCheck to test WebRTC, TURN, and UDP vs TCP connectivity. This will show if packet loss is happening on the network path. • Check network path: switch from Wi‑Fi to a wired Ethernet connection or a different network (mobile hotspot) to see if packet loss improves. • Close heavy apps: quit other apps or browser tabs that use bandwidth or CPU (file sync, video streaming, VPN clients—even if not in use). • Restart browser and rejoin the room to rule out a transient browser/WebRTC issue. Audio-specific checks • Disable client-side noise suppression or advanced audio processing (browser/hardware settings, or app-level settings) to ensure the microphone isn’t being silenced by suppression. • Try a different microphone/headset to rule out hardware or device driver issues. • Lower sample rate or bitrate if your app exposes those settings (reduces bandwidth demand). Observability & metrics • Check participant-level stats in the session (packet loss %, jitter, RTT) from LiveKit’s SFU reports to confirm where loss occurs (sender → SFU or SFU → receivers). • Note timestamps and participant IDs when loss occurs so we can correlate with SFU metrics. If packet loss persists, please tell me: • Whether loss shows on your local publish (only your outgoing audio) or on others receiving you. • The results of ConnectionCheck (or a screenshot) and any SFU stats you can share (packet loss %, jitter, RTT). • Whether switching to wired or a different mic changed anything. I can then suggest targeted next steps (TURN changes, codec/bitrate tuning, or deeper network diagnostics).
