Read alignment warnings when using Wwise with Unreal Engine packages

0 votes

Hello,
I noticed that Wwise 2023.4 IO on causes Unreal engine 5.2 to spam errors about alignment issues.

LogTemp: FMicrosoftReadRequest request was not aligned. This is expected with loose files, but not a pak file.

A example callstack when the warning occurs:

It's on a Microsoft platform with IoStore enabled on a Test Package.
Are there any known issue with Wwise 2023.x and read alignment?

Thanks
