My custom sound won't work?

[Adny]

If Harthex's advice doesn't work, try setting the priority to 0 or 1. Oh, and also, the max volume is 1.0f, putting anything above that is pretty much useless. One last thing, if you're using PlaySoundAtEntity and actually want to make it sound like it's coming from a specific entity, make sure "Use3D" is true instead of false.

Also, did you properly convert the sound into an .ogg or did you just try to rename it? If not, I'd suggest using Audacity, it's lightweight and ideal for editing your own sounds.
