Wwise Help

Probable causes:

• Too many API calls are made in a single game frame. This is most common reason this error is reported. Usual suspects are redundant calls to SetPosition, SetRTPCValue, SetSwitch, and the like. This also happen while setting up a "level", creating lots of Game Objects, setting their position and RTPCs before the actual game process starts.

• Memory intensive API calls are made, with huge numbers in the parameter arrays (such as SetMultiplePositionsor geometry calls for Spatial Audio).

• The audio processing thread is very busy, preventing processing of commands. This error would be accompanied by a Voice Starvation error if that is the case.

• The audio processing thread is blocked or deadlocked. This is indicative of a bug in either the game or Wwise itself.

Recommended resolution steps:

• Profile the API calls the game is making by enabling API Calls in the Profiler Settings (Alt-G). This can be used to identify which game process is flooding the queue with API calls.

• Review the way the game updates the Game Syncs (States, Switches, Game Parameters) for Wwise. Update these only when necessary.

• Add intra-game-frame calls to AK::SoundEngine::RenderAudio to split a game frame into multiple audio frames. RenderAudio only marks the end of a collection of API calls that pertain to a game frame. It will trigger processing of the Audio command queue to update the internal sound engine state, but no actual audio is rendered by that function call.

• Make sure the audio processing thread (named AK::EventMgrThread, but whose priority is set via AkPlatformInitSettings::threadLEngine) has a high enough CPU priority to process. If this was the problem, the game would also experience a lot of "Voice Starvation" errors too.

• Connect a debugger to the game and validate that the thread named AK::EventMgrThread is actually running. If it isn't, it would imply the game already lost all sound. If this is the case, contact Audiokinetic Support.

• Increase command queue memory size, see AkInitSettings::uCommandQueueSize .
