Something I've been experiencing since FH2 came out years ago, but only now thought about making a thread on.
Some sounds in tanks, like the ones heard when reloading or changing shells, don't play correctly when playing on a server. I can hear them fine on my own local games, where I try out stuff, but when online, they either don't play or are cut off a second after starting.
This happened on three different PC builds with three different sound sources: Soundmax chip, Realtek chip and now a Creative soundcard.
