EAX (OpenAL EFX) doesn't work in Anomaly at all.

[mfb-fake]

EAX in Anomaly doesn't work even when there's a level that has these sound environment files which EAX will use as map info and do the reverb effects from there. I tested it myself on my levels which has these snd_env files, and it doesn't work at all even when EAX is enabled from in-game settings. Looking at the console, it shows that EAX isn't enabled even when the console command for it is enabled. (snd_efx on/off, 1/0)
