Thanks for the reply, I’ve been doing some more testing. It looks like it’s not memory related.
Exactly my thoughts, if there are hard references (which there are), it should be in memory. I also added some ‘Begin Play’ Nodes that reference the sound que to ensure it is loaded.
It is pretty inconsistent unfortunately and I can’t really find the culprit; it only seems to happen on the ‘first interaction’ and is inconsistent in reproduction. After the first interaction, it reliably plays every time. It exists in cooked builds and in-editor, with no errors or remarks in the output log.
Has anyone else had a similar issue? Any ideas how to debug? I use the source build of the engine if there is some clever way to see what exactly is happening
