If a "0" effect sound is playing, Oculus Audio refuses to spatialize anything

[mcclure]

Remember: A sound with effects value "0" is not the same as NO_EFFECTS. NO_EFFECTS is when you opt out of effects. "0" is when you select {} for your effects and turn none on.

If even one such sound exists while using the Oculus spatializer, all other (or possibly just all successive?) spatialized sounds will not play. The "0" sound will be spatialized, and the others will just be silent.

This bug is almost certainly inside Oculus Audio, so it's probably my job to fix.
