[omnidisc] device preference not saved

Error message

[omnidisc] device preference not saved

What it means

Logged in setDevice() when the backend call succeeded (device switched) but persisting the preference via updateSettings({ omnidisc: { voice: { [key]: id } } }) failed. The device change is active for this session only; it will not survive restart. Non-fatal warning; null is still returned so the caller treats the switch as successful.

Solutions

1. Check errorText(e) to see whether the settings write failed due to permissions or parsing.
2. Verify the settings/config file location is writable by the app user.
3. Fix or delete a corrupted settings file so the store can rewrite it.
4. Queue a retry of updateSettings and re-attempt persistence on next app start.
5. Surface a 'preference not saved' toast so users know the change is session-only.

Example fix

// before
try {
  await updateSettings({ omnidisc: { voice: { [key]: id } } });
} catch (e) {
  console.warn("[omnidisc] device preference not saved", errorText(e));
}
// after
try {
  await updateSettings({ omnidisc: { voice: { [key]: id } } });
} catch (e) {
  console.warn("[omnidisc] device preference not saved", errorText(e));
  toast("Device changed, but the preference could not be saved.");
  scheduleSettingsRetry({ omnidisc: { voice: { [key]: id } } });
}

// ensure settings store is writable before switching devices
const writable = await settingsStore.canWrite();
if (!writable) toast("Settings are read-only; change will not persist.");

function isWriteError(e: unknown): e is { code: string } {
  return typeof e === "object" && e !== null && "code" in e &&
    String((e as { code: unknown }).code).match(/(permission|readonly|access)/i) !== null;
}

try {
  await updateSettings({ omnidisc: { voice: { [key]: id } } });
} catch (e) {
  console.warn("[omnidisc] device preference not saved", errorText(e));
  scheduleSettingsRetry({ omnidisc: { voice: { [key]: id } } });
}

When it happens

Trigger: Calling setDevice(kind, id) when updateSettings throws: settings file unwritable, settings store/backend error, disk full, or serialization failure.

Common situations: Read-only config directory or restrictive file permissions; corrupted settings JSON on disk; settings backend temporarily unavailable; disk quota exceeded.
