How to add sound?

I made a map with mortars and a flying plane(stuka).i tried to add sounds but they doesn't work and idk the problem.
the .csv looks like this :

name,sequence,file,vol_min,vol_max,vol_m*od,pitch_ min,pitch_max,dist_min,dist_max*,channel,type,prob ability,loop,mastersla*ve,loadspec,subtitle,compre ssion,seconda*ryaliasname,volumefalloffcurve,start dela*y,speakermap,reverb,lfe percentage

stuka,,Stuka/stuka_planeby3b.wav,,,,,,100,800,auto,streamed,,,, mp_abc

#ambients,,,,,,,,,,,,,,, incoming_mortar,,Explosions/artillery_incoming01.wav,1,1,,1,1,5000,6000,auto,s treamed,,,,mp_abc,,,, explosion_ground,,Explosions/Mortar_dirt01.wav,1,1,,1,1,5000,6000,auto,streamed ,,,,mp_abc,,,,

(map called mp_abc cuz i didnt find a title yet xD)

you need a script to go with that soundalias... also i dont know if stuka soundalias is already used some place else...

Mortar sound works now but stuka still doesnt :(

show your code. And you placed the stuka_planeby3b.wav in sound/Stuka with capital S?

i noticed yesterday that the sound worked but only if u are near the stuka. Then i got help and used another methode, now everyone can hear the sound :)
