EDIT: Never mind, I’m an idiot. Pitch was occasionally being set to zero.
Does this happen at random times or to specific Sounds. Maybe you are trying to play the sound before it is loaded, and then it gets stuck at 0?
Do you have lots of different sounds play at the same time?
I had some issues with sounds not playing at certain times, when the total number got higher. I am afraid I can’t narrow it down further than that. I believe there are a limited number of hardware channels and you may have gone over this.
Have a look at:
You can set which sounds are more important than others.
This may not be the case for you, but it is worth a look.
