I’d like to define arbitrary loudspeaker layouts in Fmod rather than using the pre-defined layouts provided (stereo, 5.1, 7.1). For example i’d like to try 11.1 surround sound in my Unreal games.

Does anyone know if this is posibble?

You can do this in the low level API, but the studio UI is hard coded to mono/stereo/5.1/7.1 at the moment in terms of authoring.

If you use the low level API you can use FMOD\_SPEAKERMODE\_RAW and System::setSpeakerPosition to set up your own 11.1 setup for 3d sounds.  
You’d have to use setMixMatrix to pan things the way you want for 2d sounds.
