I have exact the same problem! I already made a report but up to now i didn’t get any response from the support.
I normally play with the “lowest latency” sound-option…and then the sound crashes in the above mentiond big events…if you put it on “most stable” BEFORE the event the sound will not crack…at least in 9 out of 10 times. Still…if the number of players, and therefore effect sounds, is to high the sound will crash anyway.
Hope they will be able to fix this.
