Been bugging me for a while too but thought I'd add my experience. Flying a 38 most of the time my sound gets buggy/jerky when I have damaged engines or when there seems to be a lot of explosions around. Like it starts cut cut cut cutting out. Last night I was RTB with a pair of damaged engines and once #2 died I only had the normal single engine damage sound.
