A_FLoopActiveSound
From ZDoom Wiki
A_FLoopActiveSound
(no parameters)
Plays the actor's active sound, if one is defined. The sound is only played if the current tic is evenly divisible by eight. Contrary to what the name of this function implies, the sound is not looped. The only standard class that uses this function is WaterDropOnFloor, which uses it to make the sound slightly less repetitive.
For general sound playback, you probably want to use A_PlaySound instead.
