    v0.1.9 — recover stale receiver sessions, Reconnect menu Stable

    serrebi released this 2026-05-06 11:56:07 -07:00 | 11 commits to main since this release

    Fixes a bug where the receiver showed as connected but never played audio after the sender came online, until the add-on was manually reloaded.

    What was happening

    The receiver registered fine, but UDP heartbeats to the relay can be silently dropped by NAT/path issues without raising any error in the helper. After 15 s of dropped heartbeats the server timed out the receiver's UDP session, so when the sender's packets arrived the server had nowhere to forward them. The receiver's helper kept listening on a session the server had already forgotten.

    Helper changes

    • TCP and UDP heartbeat loops now catch send errors. On failure, the session tears down cleanly and the add-on's existing auto-retry kicks in (about 5 s).
    • The UDP heartbeat now also re-sends a UDP register packet about every 15 s, so the relay refreshes the receiver's session even if individual heartbeats are lost.
    • UDP heartbeat interval capped at 3 s (was 5 s) so path flaps are detected sooner.

    Add-on change

    • New Reconnect audio entry in Tools > NVDA Remote Audio. Stops and restarts the helper using the current role. Recovers from a stuck session in one click without reloading plugins.

    Install
