On and off for other people in my group just recently all of a sudden it did fix it self after the last big patch but i still have other people in my group that still suffer from the error.

I have the same problem any unit i place down we can hear their guns until switched doesn't matter if its vanilla or and mods that include weapons. this should be a top priority to fix.

I see another ticket was linked related to this, all of a sudden whenever i switched weapons in multiplayer, with or without mods, before and after re-install the sound of weapon is inaudible to my friends i see this bug is also from last year as well

Ticket # 0016326 Player gun sounds are inaudible after weapon switch

edit: also same problem in current dev build this issue needs fixed asap
JSRS was a temp fix for one person but not others. hows this bug even been looked at after being grouped in here with a metric ton of other sound issues?
