Need help with sound in Shadow Madness on epsxe 1.7.0

When a monster attacks/before a random encounter, there is a roar/howl sound that tells you to crouch if you don't want to fight the monster.
I do not hear that sound when I am using epsxe 1.7.0 and I cannot avoid the monster encounters. Before i used pcsx and the sound before a battle was working and allowed me to avoid unnecessary battles.

Please tell me what I have to do to make the sound work on epsxe 1.7.0
