Unreal Engine 4.26.2 Error: Skipping media load. DataChunks.Num()=1; LoadedMediaData=0

+2 votes
Hello, I've been running a ValidateLevelsTask to validate the levels in my Unreal project, and previously this worked fine, but after upgrading Wwise to 2021.1.9, I've started getting the following error: Error: Skipping media load. DataChunks.Num()=1; LoadedMediaData=0. I've re-generated all of my audio, but I can't seem to get this error to go away. Any suggestions on a fix?

The error log line should also print information about the parent asset for the media data as well as the MediaMemoryManager. Can you post the full log line?

Also what exactly is your ValidateLevelsTask doing and when is it being run? Is it run in a commandlet?

I just get a bunch of stuff like this:

This task is being run as a commandlet prior to us doing a full cook/package of the game.  It gathers all referenced actors in each map and then calls CheckForErrors on them, logging out the errors and fixing up any if possible.

This bug was fixed in Wwise 2021.1.10, see WG-61029 on this page https://www.audiokinetic.com/library/edge/?source=UE4&id=releasenotes.html.

If you are unable to upgrade at this time, you could always just downgrade the log severity to "Log".

This also occurs when running with -nosound, should that be added to list of checks?
