Quick answer: Resolve voice-over clips through the same line ID and active-locale lookup as subtitles, with a fallback to the original-language audio when a dub is missing.
Subtitles in French over English audio break immersion. Resolving voice clips by locale the same way you resolve text fixes it. Here is how.
How to fix it
1. Key audio by line ID and locale
Store voice clips under the dialogue line's ID per language so the audio system resolves the same key the subtitle system does for the active locale.
2. Fall back to the original-language audio
When a localized dub is missing for a line, play the original language clip and keep showing the translated subtitle, rather than silence or a wrong clip.
3. Separate voice locale from text locale if needed
Some players want translated text with original audio; expose a distinct voice-language option so audio and subtitle locale can differ intentionally rather than by bug.
Catching the ones you can't reproduce
The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.
Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.
This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
The errors you never hear about are the ones quietly costing you players. Visibility turns them into a worklist.
