Wwise Unity Timeline Event Duration Not Associated with SoundBank

Question

I'm trying to integrate Wwise events into Timeline for a feature set. But I'm running into an issue where when I set an event on Timeline, it is not able to associate the event with a duration. I have regenerated all the sound banks with the setting, "Generate XML Metadata" enabled. I've also made sure that the "Estimated duration" is enabled in the "Metadata Options" section. So all that data should be getting generated appropriately. In Unity in the `Wwise Picker` I have it set to populate using the `File System`.

I don't know what else to try as I just continue to get the following warning without any kind of instructions to be found:
"The duration of the Wwise event "<event name>" has not been determined. Playback for this event may be inconsistent. Ensure that the event is associated with a generated SoundBank!"

I do not know how to make sure that the event is associated with a generated soundbank as I thought it was upon generation. Any assistance will be greatly appreciated!

Anybody? Beuller?

Was this ever solved? We are running into the same issue.

Answer 1

I have the same issues... The "Estimated Duration" is enable in my "Metadata Options". I also checked my "SoundbanksInfo.json" files and all the duration info are inside.

Answer 2

Hey, I found why this doesn't work. There is a bug in the AkWwiseXMLBuilder at the function SerialiseSoundBank(): the node should select "Events" instead of "IncludedEvents".

Regarding this bug, Wwise fixed it in Wwise Unity Integration 2022.1.5.8242.2798  (released circa summer 2023)
WG-63156 Fixed: SoundbanksInfo.xml is not parsed or put into Unity cache.

The bug was that Wwise updated the .xml format from "IncludedEvents" to "Events" but not the Unity integration code, thus it still expected "IncludedEvents" and thus did not parse the events.

This bug seems to have introduced in Wwise version 2022.1
WG-57936 SoundBank generation metadata files have been overhauled: ...

I reported this bug via Wwise Launcher in December 2022 with number 1670h5-45645-22226-71818
