This is what happens in our project when switching screens while any audio such as music is playing when using built in sound components.
Most of those larger gaps are switching screens with “async” loading enabled. Latest engine version.
You can hear / see that even small hitches in the game sim mess up the audio. This highlighted section isn’t even a screen change. You can heart in the audio sample above.
This is with keeping all sound components loaded at the same time too. If I only keep a single sound component loaded (based on collection proxy loading/unloading) it makes the game sim hang while changing songs too (and any other audio which happens to be playing sound glitchy).
