I am really excited I bumped into this mod as I played a server over a year ago and just loved the sound effects.  I thought maybe the graphics on explosion were different than standar also but not sure on that one.

At any rate just installed on a server I am building and somehow just does not seem right.  Sound is definately standard.  Pasted below the json config file if it helps.  Hope we can get this working again its one awesome mod.

{
"Settings": {
"Ammo Types": [
"ammo.rifle.explosive"
],
"Explosion Effect": "assets/prefabs/weapons/beancan grenade/effects/beancan_grenade_explosion.prefab"
}
}

That prefab may have changed, so there'd be no sound if it doesn't exist. You can look for other "sounds" using the Prefab Sniffer plugin.
