Sound Sync - Multiplayer - Sync/Direction/etc

The sounds of animals do not correspond to the direction they are coming from, you just hear the sound when they are somewhere somewhat nearby. When playing 2+ player missions, the sounds are not heard at the same time by each player, even if they are next to each other. For example I might hear a Bear and say over the headset "I hear a bear" - but the other players hear nothing, for maybe 10-60 seconds later. Can the sounds be synced?
