Hi, Im’ fighting with project XBOX ONE deployment with Fmod and UE4.22 (fmod 2.00.06)  
What i did so far:

- plugins files in proper places
- missing dlls: added lines to cs files (fixed one of my previous problem with missing dll files, engine rebuild)
- added line in config file to disable default unreal audio

And now I have something about XMAAudioInfo.cpp  
and line 72…

From xbWatson log:  
`LogXboxOneOutputDevices: Error: === Critical error: ===`  
` LogXboxOneOutputDevices: Error: LogXboxOneOutputDevices: Error: Fatal error: [File:E:\UE-4.22.3-release\Engine\Source\Runtime\XboxOne\XMA2\Private\XMAAudioInfo.cpp] [Line: 72]`  
`LogXboxOneOutputDevices: Error: Failed to create APU heap: 8aca0001`

from UEditor log:  
`LogSockets: Error: Unable to read full network header`

Game is starting with Fmod plugin disabled so it must be something wrong here

It’s like that FMOD has already initialized the XAudio2 module and Unreal do not detect this trying to re-initialize it again.  
If you use only FMOD for ANY sound you can disable XAudio2 inside your XboxOneEngine.ini file adding these lines:

[Audio]  
AudioDeviceModuleName=  
AudioMixerModuleName=

Bye,

Thank you so much for this, I just had the exact same issue.

It would be awesome to get this added to user guide alongside AudioDeviceModuleName - [https://www.fmod.com/resources/documentation-ue4?version=2.0&page=user-guide.html](https://www.fmod.com/resources/documentation-ue4?version=2.0&page=user-guide.html)

We had the game working with 4.21 but upgraded to 4.24 recently and it seems this step is required for Xbox UE4.22+

Thanks, I’ll get this added to the docs for the next release.
