  • WG-60212 Fixed: Crash after attempting to load an incompatible Profiler session after a first successful session load.

Fixes for Community-Reported Bugs

  • WG-52903 Fixed: Project Explorer doesn't restore expanded states correctly.
  • WG-59422 Fixed: Crash when combining finite Sequence Containers that have Trigger rate transitions with Blend Containers that have Initial Delays.
  • WG-60577 Fixed: Crash when deleting a Music Track while its volume slider is active.
  • WG-60602 Fixed: Out-of-bounds memory access when encoding very small (<960 samples) sources with WEM Opus.
  • WG-60945 Fixed: Game-Defined Auxiliary Sends don't get regular updates from RTPCs on busses.
  • WG-60969 Fixed: (Spatial Audio) Any emitter using diffraction can become inaudible when the listener position overlaps a portal.
  • WG-61127 Fixed: Crash in CAkListener::MultiDirectionGainCorrectionForObjects during low-memory scenarios.
  • WG-61304 Fixed: (Spatial Audio) Diffraction path might be dropped and transmission loss goes to 0% when listener and emitter are in different rooms but on the same side of a portal.
  • WG-61508 Fixed: SoundBank metadata Max attenuation for Events does not take Post Event actions into account.
  • WG-61597 Fixed: Streaming media can be stopped if inspected by the garbage collector at the wrong time. Added more detailed logs to the AkUnrealIOHook.
  • WG-61634 Fixed: Crash when inspecting an RTPC or State from the Multi Editor or the default plug-in property list.
  • WG-61655 Fixed: Calling AK::SoundEngine::ReplaceOutput with an Audio Device ShareSet of 0 can cause audio loss if the old output Audio Device is connected to multiple audio busses.
  • WG-61686 Fixed: External Editor doesn't work on Music Clips and Music MIDI Clips in the Segment Editor.
  • WG-61687 Fixed: WAQL originalFilePath doesn't work for MusicClip and MusicMidiClip.
  • WG-61706 Fixed: Crash when Opus sounds start in virtual mode.
  • WG-61727 Fixed: A nested Music Switch Container doesn't switch to the correct child when the parent Switch Container has an active Transition with a positive Offset.
  • WG-61850 Fixed: (Spatial Audio) Any emitter using diffraction can become inaudible when the listener position overlaps a portal.
  • WG-61981 Fixed: Crash due to memory stomp inside of CAkTransitionManager::TermList when shutting down the sound engine.
  • WG-62017 Fixed: (Spatial Audio) AKASSERT(portalPath.IsEnabled()) in the function AkAcousticRoom::InitContributingPortalPaths.
  • WG-62057 Fixed: Erroneous Seek Table Absence warnings occur when replaying Vorbis files from the beginning.
  • WG-62149 Fixed: Imported SoundBank files can be linked with the wrong WwiseAddressableSoundbank if the former's name is a substring of the latter.
  • WG-62150 Fixed: Using S-Curve Interpolation on RTPC curves provides values outside the specified range in some cases. For example, it might generate negative values for Spread or LPF/HPF factors when the curve should stop at 0.
  • WG-62177 Fixed: Setting a bus configuration to Same as passthrough mix when 3D Audio is available but passthrough is not available sets the bus configuration to Audio Objects instead of setting it to the Audio Device's main mix.
  • WG-62358 Fixed: Crash due to stack overflow originating from CAkVPL3dMixable::GetVolumes in some scenarios.
  • WG-62383 Fixed: File Packager takes a long time to complete when there are many excluded memory files in a single SoundBank.
