Hey everyone,

I’m developing a Unity game (using FMOD Unity integration, latest version on Unity 2021.3.45f2 LTS) for Xbox/PC, and I’m hitting this annoying FMOD error spam in the console: `[FMOD] SystemI::updateChannels : Channel 0xB205F9 Stolen with audibility 0.158352`. It happens frequently during gameplay, especially with multiple sounds like footsteps, ambient effects, and music overlapping.

Not only is it flooding the logs, but my game starts lagging badly – frame drop and getting stuck for 20-30 second on the XBOX. Audibility is low, so it’s virtual voices getting stolen by higher priority ones, I think.​

**My Setup:**

- Unity 2021.3.45f2 LTS

- FMOD 2.02.30

- Target: Xbox GameCore + PC builds

This is correct, these warnings will only appear in Debug/Development builds and not when using the Release libs. You can also adjust the number of real and virtual instances available in the FMOD Unity Settings.
