I have a clip (aCameraSnap, of the ExtraSounds category) which was fading out/silencing all other clips in a room -- which were also ExtraSounds, hence the error.
I made a category called Special, with only this clip listed in it, and given infinite sound clips to the Special channel. Now, it *doesn't* play, while all the other sounds keep playing as usual -- but *only in this room where the original error above was happening*
What's going on? Is it solvable?
How many channels are you using for each type?
Remember that there are only in total 8 channels (think this hasn't changed yet).
1 is reserved for Speech
Assuming you have 1 for music and 1 for ambient, that leaves 5 for sound.
How many do you have for ExtraSounds?
Leaving Special at 0 means it'll use whatever is not in use. Try setting it to 1 and see it if that helps
