Hi everyone!
In our company we have discovered a bug after Oculus latest firmware update. Everytime an Oculus headset is plugged into the computer, sound in editor gets disabled. Not only are sounds not played in game preview but the play option in cues and master files become unabled. When the headset gets unplagged, UE4 goes back to normal.
We were able to reproduce this issue in versions 4.23 and 4.22 in two different computers.
