No Audio in Standalone

I have a basic project running with spatial audio. The audio works as expected in the viewport and PIE windows, but when I play it in Standalone mode there is no audio output. I’ve taken a couple of troubleshooting steps:

  • Used the Get Current Audio Device Name in a Blueprint to confirm the correct audio output device is being used.
  • Used Audio3DVisualize to show the sound sources, which indicate the output appears to be working properly.

Not sure if this is a bug or something I’m overlooking. This is being seen in UE5.0.3 on Windows 10.
