Do local sounds still work?

I've tried everything I know, but I can't get a sound to play inside the PlayerGui, or just inside the player. That used to be how you'd make local sounds, but I need to know if there is a different way now. Please help! Note: That the "IsPlaying" value of the sound is true, it just never plays. I've even tried it in test solo mode so that I could see all the properties.
