Sound (For Players Ear Only)

[span]

Hi, this might just be me that's missed something very obvious. I've created custom sounds and successfully used them in my map.
But i want to be able to play these sounds for "players ear only" when they trigger a cirtain multiple... and not play the sound out loud for everyone. I couldnt find a flag option allowing me to do this as there was before.

Any way to fix this? via lua or are there other options i haven't yet discovered? /Thanks.
