After january patch, some weapons (mod or vanilla/original ) don't make sound on single shoot.
I try with and without mods .. after the patch .. sometimes i don't hear the sound of shoot of my mates (random), and sometimes (always random), I hear a continuos sound like empty magazine (click click click). When my mates change the fire rate... I hear the sound.... I can't explain it... but it happens to many.
I checked files on steam, re-downloaded all mods (server and local), but no changes.. seems to be a random thing. (especially especially when using a silencer mod or vanilla)
