Notes:
As this was discovered during testing of [Internal link], there is already a test for this. When a fix is ready, re-enable the currently ignored test case ToggleEnabledStateOfGeneratorOAFR_WhilePlaying_AffectsSignalAsExpected(Prefab,AudioListener,Disabled). This is done by removing the conditional [Internal link].
