Making classic ayo-wololo mod work

Dear all,

I would like all my monks and all the enemy monks to convert using this sound.

I've installed a mod in-game, created a scenario with a vil and a monk vs a vil and a monk, and neither mine, nor opponent's monk use the old sound.

Furthermore, it also doesn't seem to work in Joan of Arc campaign.

What am I doing wrong? How to change sounds of the new monks to the sound of the OG monk?
