I tried removing my HDMI cable, use head phone and speakers, but the problem is the same.
I don't know If it would be useful, but here is the Audio.log file the mod creates, I think it may help solve this problem.

Also the Hext.log and The_Reunion.log doesn't show any error, the Audio Replacement load just fine.
