Good afternoon!  
When playing a large number of the same events (Instance and Priority are configured), this warning pops up and the sound starts “crackling” and plays incorrectly.  
Is it possible to increase buffer and will it help to get rid of “crackling”, “jamming”?  
i use Fmod studio 2.01.11 vers.  
unity vers: 2021.2.6f1

It depends on how many events is “a large number”. It would be best to record a Live Update profiler session to get an accurate look into what could be causing such cracking noise. You can see how much resources are being used and the volume of your events.
