Odamex 0.8.1 demo displaying the platform sound bug
Sometimes when you raise or lower a slow moving platform, the sound of the platform moving never ends despite the movement of the platform ending. Also, the sound effect to denote the end of the platform moving never plays. I have included a demo of doom2 map11 experiencing the bug in Odamex 0.8.1 release.
