Footstep Sounds

I’m using some footstep sounds here and have things the way i’d like in terms of sound randomization, timing, etc… my problem is that the VOLUME always seems to be the same, even if I set volumn = 0.15f or something suitable low.

Is there something else i’m missing here? I’d like my footsteps to have a much more muffled/quiet sound to them.

I use a custom rolloff with a distance of 50, and in my script -

audio.volume = 0.5;
