custom TTT grenade explosion sound won't work

[KTBM]

No errors are displayed it's just that the sound never played when the grenade explodes
here is my code
[lua]AddCSLuaFile()
resource.AddFile("sound/soundFile/soundName.wav")

ENT.Type = "anim"
ENT.Base = "ttt_confgrenade_proj"
ENT.Model = Model("models/weapons/w_eq_fraggrenade_thrown.mdl")

function ENT:Explode( tr )
if SERVER then
self:SetNoDraw( true )
self:SetSolid( SOLID_NONE )

if tr.Fraction != 1.0 then
self:SetPos( tr.HitPos + tr.HitNormal * 0.6 )
end
local pos = self:GetPos()

local effect = EffectData()
effect:SetStart( pos )
effect:SetOrigin( pos )
effect:SetScale( 500 )
effect:SetRadius( 500 )
effect:SetMagnitude( 300 )

sound.Play("soundFile/soundName.wav", pos, 100, 100)
util.Effect( "Explosion", effect, true, true )

util.BlastDamage( self, self:GetThrower(), pos, 500, 300)

self:SetDetonateExact( 0 )

else
local spos = self:GetPos()
local trs = util.TraceLine( { start=spos + Vector( 0, 0, 64 ), endpos = spos + Vector( 0, 0, -128 ), filter = self } )
util.Decal( "Scorch", trs.HitPos + trs.HitNormal, trs.HitPos - trs.HitNormal )

self:SetDetonateExact( 0 )

end
end

[/lua]
I've checked that the spelling of the sound files is fine but they were fine.

Use Entity.EmitSound instead.

Sadly that did not work.

Are you sure the sound is being downloaded to players? Any red message about in console about missing file?
