Built-in Reverb not working in packaged builds? - 4.26

Hi guys,

I am currently having a frustrating issue with Unreals built-in reverb not working in packaged builds (Windows 64bit). I have already tried a handful of fixes, none of which have solved the problem. Reverb is working as intended when playing in editor and the au.Debug.SoundReverb console command shows that ‘Reverb_Master’ is active. In the packaged build this command states that no reverb is active

The setup is as follows. Created Master_Reverb asset, assigned this to World Settings > Audio > Reverb Effect, enabled relevant SoundClasses to be sent to this reverb, set up ‘Attenuation Reverb Send’ values in relevant SoundCues.

I have tried:

  • Enabling the ‘built in’ reverb plugin under Project Settings > Platforms > Windows
  • Adding the following commands to the WindowsEngine.ini file

[Audio]
AudioDeviceModuleName=XAudio2
AudioMixerModuleName=AudioMixerXAudio2
UseAudioMixer=true

  • Used ‘au.disablereverbsubmix’ / ‘au.disablequadreverb’ / ‘au.disablelegacyreverb’ console commands while playing the packaged development build to try and disable any features that may be stopping the reverb from being activated.

Any insight would be much appreciated as I’m not sure what else to try.

Cheers!

Bump. Also would like to know if there is a fix to this. Using 4.27
