PrecacheScriptSound doesn't work

[kadet.89]

CS:S
PrecacheScriptSound("BuyPreset.CantBuy");
when I try to play the sound, I get this error:
SV_StartSound: BuyPreset.CantBuy not precached (0)
I tried to use detor for PrecacheScriptSound, but doesn't work either

What command are you using to play the sounds?

PrecacheScriptSound is meant to be paired with the EmitGameSound* family of functions.
