# ❓ 7. FAQ & Troubleshooting

**Q: I get a `DllNotFoundException: fmodstudioL` error.**\
**A:** You forgot to import the native libraries. Download the official FMOD for Unity package and import only the `Plugins` folder into your project.

**Q: My background music is being culled/muted when I move the camera!**\
**A:** Your music event is being treated as a 3D sound. Open FMOD Studio, select your music event, and **delete the `Spatializer` effect** from the Master Track. Rebuild your banks. The system will automatically detect it as a 2D sound (`MaxDistance = 0`) and disable culling for it.

**Q: When I spawn 1,000 enemies, some sounds don't play or cut off abruptly.**\
**A:** You are experiencing "Voice Stealing Thrashing". FMOD has a hard limit of 256 channels.

1. Open FMOD Studio and reduce the `Max Distance` of your enemy sounds so they cull earlier.
2. Set `Max Instances` (e.g., to 20) in the event's Macros, and set `Stealing` to `Virtualize` or `Furthest`.
3. Ensure your looping sounds have a **Loop Region** on the FMOD timeline, otherwise, they will die naturally while virtualized.
