To Whom It May Concern,
While upgrading to 2017.1.3 it turns out the integer index for listeners casts fine to AkGameObjectID so it took a bit of hunting to find the cases. Unfortunately when the error comes through the callback set by SetLocalOutput, the callback doesn't include the listener index or information for the call itself (setting obstruction/occlusion, etc) that the bad game object id was in fact the listener game object id instead of the emitting game object id and what it actually has for that value.
Thank you,
Brent
