Windows Update borked my audio

not sure if this is the proper place, but few days ago I did an innocent Windows Update and now the engine will NOT play audio. Literaly, just clicking play on asset in Content Browser, nothing. Has anyone else run into this?

  • Audio is fine in other applications

Hello there @jsunandmax!

No worries, Windows updates tend to create the most bizarre scenarios. In this case, it’s possible that your Audio Mixer was disabled by the update. Check your WindowsEngine.ini file, you should have this line under the Audio tab:

AudioMixerModuleName=AudioMixerXAudio2

If this isn’t the case, and you have already checked for potential driver issues, try the following:

  • Open Unreal Engine.
  • Press Win + G to open the Xbox Game Bar.
  • Click on Audio and check if Unreal Engine is muted.
  • Plus, open the Volume Mixer in System Settings to check the same.

thanks for fast reply. I did not have a ‘WindowsEngine.ini’ (guess it’s only created if you have platform-specific overrides?) so I created one in my:

C:...\ projectname\Config\Windows

inside the .ini i have:

[/Script/Engine.AudioSettings]
AudioMixerModuleName=AudioMixerXAudio2
bEnableAudioMixer=True

I closed engine, restarted, still no audio.
thats it. The xbox thingy didnt do anything (wasn’t muted).

But did a full system reboot and… IT WORKS! THANK YOU!
