Yes
Performance degrades and FPS decreases when adding a lot of inactive AudioSources to a Scene with Audibility Computation taking 11ms
Steps to reproduce:
1. Open the attached user's project "1657950_Gavin.zip"
2. Open "SampleScene.unity" and enter Play Mode with Game View Stats turned on
3. Observe in the Profiler CPU Module and Audio Module
Expected results: No performance hit and fps does not decrease when adding more inactive Audio Sources to the Scene
Actual results: Performance degrades and FPS decreases when adding a lot of inactive AudioSources to a Scene (See attached Results.png)
Reproducible with: 2022.1.0a3, 2022.3.10f1, 2023.1.16f1, 2023.2.0b12, 2023.3.0a8
