Issue
Looping audioEmitter sound does not fade with levelinfo->sound->soundDistanceModel set to Logarithmic. Plays like it's a 2D sound and not a 3D sound.
Repeat
Place looping3D audio emitter ingame with levelinfo->sound->soundDistanceModel set to Logarithmic. (might have to save and restart first)
Suggest
Make it fade out like it does in linear

So it's an Fmod issue?

Well, it's how logarithmic sound falloff works (not just in FMOD). The volume simply halves every min distance steps. Since with this model in a limited-precision environment the sound may reach zero volume only very, very far from the sound, the max distance settings acts as a limiter to distance attenuation. Usually this is implemented by the sound retaining its attenuated volume for any distance greater than max distance. DS is the only exception that I'm aware of that allows cutting sounds to zero volume at max distance in this model.
Much more than linear attenuation, logarithmic attenuation depends on good min and max settings.
