OpenAL Soft doesn't support the EAX extension, which was essentially 
grandfathered in from DirectSound to help ease early porting efforts for 
apps that used DirectSound+EAX. The EFX extension is the preferred way 
to use environmental audio effects with OpenAL, which is just as capable 
and is supported by OpenAL Soft, Rapture3D, and the Generic 
Software/Hardware devices.

The log shows EFX is being used:

It's interesting that for "Generic Hardware" it says "EAX reverb support 
enabled" even though it supports EFX too. I wonder what the difference 
is for the game.
