Whenever a player fires at a texture, only textures designated as "concrete" and "metal" (in the materials.txt file), will play a ricochet sound.

All other textures will play the footstep sound that corresponds with that texture.

An easy way to reproduce this bug is to fire an LMG at a ladder. One of the pl_ladder*.wavs will play.

In the sounds\weapons folder are ric1.wav through ric5.wav, but these do not seem to be used at all. Only ric_conc-1, ric_conc-2, ric_metal-1, and ric_metal-2, play for concrete and metal textures, respectively.
