Play around with some of these (be sure to remember/write down the defaults) might help a little. But also yes the sounds are a bit random at times but that's mostly because the different types of mercs also make different footstep sounds(speed etc) so it just takes getting used to. Still better than CSGO footsteps xD

edit: (ps: those are the audio commands for the engine, some may not work if SD disabled them for DB :p)
