Referenced events causes more delay on playback

FMOD Studio
1

In fmod v 2.02.30 (and 29) I have a bug:

If i play a sound from its own event, everything plays on time. But if I play a sound from a nested/referenced event, I get a delay.
In this example, I have a BP firing 2 sounds, in the same execute pin, when a specific thing occurs.

One sound is a simple event with a test tone in it.
Another sound which has a ref/nested event with a test tone in it. This test tone is pitched higher, so you can tell them apart.
In theory they should be playing at the exact same time (because they are called at the same time), but there is a delay on the nested one.

Why?

I wanted to share an audio file, but i’m not allowed to upload one. You only accept images and video files? Maybe change that in the future to include audio? :slight_smile:
Here is the sound:

Hi,

A few questions:

  • Could I get you to go into more detail about how your event is set up in FMOD Studio?
  • How is the asset being set to load in FMOD Studio? i.e. is it set to stream, or is it using compressed or decompressed?
  • Are you able to reproduce the issue in FMOD Studio, or just in UE?
  • In UE, how are you handling loading the banks containing the parent event and referenced event? Are the banks and their sample data behind loaded ahead of time?

Screenshots of how the event is set up, or a short video showing how it’s set up and demonstrating the playback delay would also be great.

Very weird. I cannot seem to reproduce the error now.

Will continue working and write here if the problem arises again.
Thanks for your time.
