Is anyone able to verify whether Microsoft Spatial Audio plugin works as intended?
The plugin is intended to allow the game to interface with Windows Spatial Audio (Windows Sonic/Dolby Atmos for headphones/ DTS :X)
The issue is that as far as i can tell the plugin no longer functions as intended. Internally it allocates an array for 40 sounds for processing and even though UE audio plugin API will properly call initialization and deinitializiation of individual sound sources, once the count of sounds played through the spatialization plugin exceeds said 40 instances it will crash when attempting to access sound object assigned on the spatial audio library side to UE audio source.
I assume this is due to some sort of API change in windows spatial sound api that’s not been reflected in the plugin as judging by documentation (Spatial audio in Unreal - Mixed Reality | Microsoft Learn) It’s been maintained under Mixed Reality team at Microsoft, which has been disbanded a long while ago and probably nobody picked it up internally.
I’ve been able to reproduce this issue in two separate projects by simple setting up the plugin and playing over 40 spatialized sounds in sequence, crashing at same spot every time.
So i would assume it’s a matter of bringing the issue to Microsoft and/or Epic delisting the plugin as no longer functional.
