Sequencer audio clips cutting out before the end of their clip in gameplay (Why?)

Hi!

Lately, we moved with our project to Unreal Engine 5.0.3 - it was almost hassle-free. We made work everything needed for our project, except for two bizarre issues we haven’t been able to solve.

The main problem right now is that every audio clip we are using in sequencer for voiceover of the characters sometimes cuts off at the end.

I made a re-import of all assets. I also downloaded the newest version of UE5 from Unreal Engine Launcher - and I can replicate this behavior in the brand new project.

Look at how it behaves here:

I really don’t know what to do, because we tried everything.

We are not using any special effects/plugin for the clips - we are using built-in spatialization, and everything is basically at default configuration at the moment.

I figured, that a good solution would be maybe to each wave clip add +0,5s blank space (aka 500ms).

The same sequence was fine without any issues in UE 4.26 and UE 4.27.

It seems to me that maybe Unreal 5 is introducing some weird new delay on some occasions, which means it will cut the clip once the sequence pointer gets exactly at the end of the time frame of the clip.

Do you think there is any way how to tackle this problem except by moving to WWISE or FMOD? Should we write a bug report?

When using exactly the same sound file outside the sequencer - any wave clip will result in no problems. No cut-offs. Or playback problems. So entire problem can be narrowed as a Sequencer problem.

Thank you in advance for any kind tip or trick regarding this.

Hey, ran into that issue a little while ago. You need to make sure the loading behaviour is set to prime on load, retain on load, or (bad idea though) force inline.
You can set that in the default sound class, or else on each wav asset, through the loading behavior override dropdown.

Try something like this on one wav to test:

fingers crossed,

Hi Thierry, I don’t know if you are an angel sent from heaven or something similar, but your solution works!

I completely overlooked these settings. But after setting it to Prime on Load - the problems with cutting are gone!

I will test it for a few days, as I want to avoid the “placebo” effect of early happiness, but if this proves to be correct, I will check your answer as a solution.

Behalf of our whole team, I thank you for your time and reply!

Whooo!

Thank you!
