WORKING: 3039270 (4.12.5)
The "Stat SoundCues" command lists all sound actors in the level, even if it's not heard by the user. In 4.12, it only listed those that were in hearing range.
Link to test project: [Link Removed]
Stat SoundCue runs, and two sound actors are listed (one which is audible to the user, the other isn't).
Only the sound actor audible to the user should be listed.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-35237 in the post.
