Hi @flashASA

It sounds like a tricky situation, but there’s a couple of suggestions that might help resolve this and understand the problem:

Check Audio Output Routing: Ensure that A2F’s audio, captured through SubmixListener, is correctly routed to your game’s main audio output.

  • Create an Audio Submix: In Unreal Engine, create an audio submix dedicated to handling audio from A2F. This submix acts as a channel to direct the audio to the game’s main audio output.
  • Configure SubmixListener: Adjust the settings in A2F’s SubmixListener to output to this new submix. This ensures the A2F audio is directed correctly.
  • Verify Routing: Check the audio settings in Unreal Engine to ensure that your new submix is properly routed to the main audio mix.

Debug Audio Path:

  • Enable Audio Debugging: Use console commands like au.Debug.Sounds 1 or au.Debug.SoundMixes 1 to activate audio debugging.
  • Visualize Audio Path: Use commands like au.3dVisualize.ActiveSounds 1 to enable a visual mode for active sounds and understand the flow of audio.
  • Check Sound Mixes and Modulations: Inspect active sound class mixes for any issues.
  • Examine Active Sounds: Use au.DumpActiveSounds to list all currently playing sounds.
  • Analyze Memory Usage: Use AudioMemReport for a detailed report on the memory usage of active sound objects.

These steps might help you pinpoint and resolve the audio streaming issue.
