I’m not sure what’s going wrong here. I havent changed any of the settings for the audio, yet I’m getting an error while compiling even though I’ve never gotten it before. Here’s where it aborts for me:

The only information I could find out about this is in here: Build failed with OVRPlugin Error - XR Development - Unreal Engine Forums
However I’m using the default icon set, so I don’t know how that answer helps me. Any help will be much appreciated
Weird. Turns out that the sound attenuation file I made for playing a sound at a location was screwing everything up. It packages properly after I deleted it… now to figure out how to play the sound and also get it to package 
The Oculus error came in when the versions between UE and Oculus fell out of sync. It doesn’t stop packaging/cooking - the error stoping your package will be elsewhere in the log. Those Oculus errors are annoying but don’t stop anything. Here is a the log from a package I build yesterday (with the project name redeacted)

You can see the Oculus errors, but also see the build was successful.
