es_stopsound

[ManifestManah]

es_stopsound does not seem to do anything. If I currently have a sound playing and I wish for it to stop playing using the es_stopsound it won't stop the sound that is playing.

This is the code I am using in my block:
es_playsound event_var(userid) ambient/atmosphere/city_skypass1.wav 1.0
es_delayed 1.5 es_stopsound ambient/atmosphere/city_skypass1.wav

I have also tried other versions, of the stopsound, inserting userids, adding 1 at the end etcetera, just to be sure the syntax wasn't just changed from the original.
Hopefully this is possible to fix :-)

(The game I tested it on was CS:GO)
