Hm, interesting. I agree that you probably shouldn’t have to dig into the settings.
Have you heard of the Unreal Slackers Discord server? Some of the UE Audio team members are in there frequently to answer questions. There’s also a Facebook group called Unreal Engine Audio Tips & Tricks where they frequently respond to troubleshooting questions.
For fast replies, those are your best options—unless someone else happens to be browsing the forums and can chime in!
