Bank failed to load(Ak_BankAlreadyLoaded) error

+2 votes
Hello!

I have been trying to integrate Wwise on Unity's tutorial game, "Nightmares". So far everything is working great, but I have just one problem. After some point (not since the beginning), the sound bank that I have attached to the player is failing to load after he dies and the game resets. I get the error "Bank Player failed to load(Ak_BankAlreadyLoaded)" message. It is a bank containing the player's footsteps,heartbeat etc.

 When I disable the sound bank on the player, I get error warnings whenever he makes a step or tries to call any sound event from the bank, but when he dies and the game resets, I don't get any messages. Like the game is not even trying to call these events. Any ideas?

Thanks in advance.

Updating this old thread, since I am seeing something similar.  It used to work before I moved the project to a new computer, and now it doesnt.

I get this warning, when I stop Play mode.  No sounds play during Play Mode (and no warnings or errors):

WwiseUnity: Bank Master_Bank failed to load (AK_BankAlreadyLoaded)

Then a number of my objects report this error:

Wwise: Unknown listener game object ID. Make sure the game object is registered before using it and do not use it once it was unregistered. (GameObject: Camera (UnityEngine.GameObject)) (Instance ID: 64266)

The events that are selected are linked through the Event objects, the project refreshes fine, says its connected, the Generate SoundBanks works cleanly (no warnings or errors), and I can play the sounds in the Events under Wwise Authoring in the Wwise Picker, but in the actual game.

I have the WwiseGlobal AkBank load on Awake.  If I change it to Start instead of Awake, I lose the AK_BankAlreadyLoaded warning, but the others still give errors, and still no sounds.  Awake is the correct event regardless.

If I find a fix I'll post it.  Maybe related and useful to someone else who searches in the future.

BTW, I feel like the Errors of the "Unknown Game Object" may be timing issues with playing the game in the editor, after a tear down of the objects, so they are not "unregistered" and being used for another frame's processing.  Not sure.  But I think the root of the problem is the WwiseGlobal  AkBank isnt properly initializing for some reason.
