[omnidisc] deafen failed

Error message

[omnidisc] deafen failed

What it means

Logged by toggleDeafen() when the Tauri IPC command `omnidisc_voice_set_deaf` fails. Like toggleMute, it optimistically sets `deafened` and reverts on failure. The user's deafen state is unchanged on the backend, and this is a non-fatal warning.

Solutions

  1. Inspect errorText(e) in the console for the backend's concrete error.
  2. Gate the deafen toggle on an active voice connection.
  3. Confirm `omnidisc_voice_set_deaf` is registered and its handler handles the not-connected case gracefully.
  4. Verify audio output/input devices exist before deafening.
  5. Avoid testing invoke() from a plain browser; use the Tauri window.

Example fix

// before
deafened = next;
try {
  applyStatus(await invoke<VoiceStatusWire>("omnidisc_voice_set_deaf", { deafened: next }));
} catch (e) {
  deafened = !next;
  console.warn("[omnidisc] deafen failed", errorText(e));
}
// after
if (!connected) return;
deafened = next;
try {
  applyStatus(await invoke<VoiceStatusWire>("omnidisc_voice_set_deaf", { deafened: next }));
} catch (e) {
  deafened = !next;
  notifyUser("Could not change deafen: " + errorText(e));
}
Defensive patterns

Strategy: try-catch

Validate before calling

if (!get(voiceConnected)) throw new Error("voice session not active");

Type guard

function isTauri(): boolean {
  return typeof window !== "undefined" && "__TAURI_INTERNALS__" in window;
}

Try / catch

try {
  applyStatus(await invoke<VoiceStatusWire>("omnidisc_voice_set_deaf", { deafened: next }));
} catch (e) {
  deafened = !next;
  console.warn("[omnidisc] deafen failed", errorText(e));
}

Prevention

When it happens

Trigger: Calling toggleDeafen() when the backend command `omnidisc_voice_set_deaf` returns Err: no active voice session, audio subsystem error, or Rust handler failure (e.g. cannot apply deafen to the audio pipeline).

Common situations: Clicking deafen right after leaving a voice channel; audio device removed mid-session; backend handler panics or command not registered; running in plain browser during dev.
