Other player’s in game voice chat can sometimes get desynced in long conversations, and listeners begin to hear fragments of conversation out of order. Here is an example of this issue: https://streamable.com/y55bre
It’s usually specific to one player’s voice chat (other players in proximity transit voice without desync), and can sometimes be fixed by relaunching the game, or running far out of distance from the player’s voice range and returning.
A console command to reset the active Steam Voice Chat connections could help mitigate this issue.
