Incidental Sounds causing overall sound issues.

It seems having either one or multiple instances of sounds with "Incidental" checked is causing other sounds, such as footsteps, to glitch or cut out. Unchecking all instances of Incidental appears to fix this.

I think we should just remove this option. It was really only useful back in the era of limited hardware sound voices. In pretty much every system, audio is now done in software with effectively unlimited voices.
