Hello, ive tryied to find some answer but i have found nothing about my problem. Ive installed fresh server following the tutorial from docs/fivem/net, the problem is : all my friends can hear me on the server but they cannot speak, i cannot hear them. Why, where is the problem ? i mention the server is installed on Ubuntu 20.04.

i found the problem, you need to enable onesync … in windows is by default in config.cfg the line “onesync_enabled true” for linux that line is not present, you need to add it, or you can use the new method by adding in +set onesync legacy in start server command line for example :
cd ~/fivem_resources && bash ~/fivem_server/run.sh +exec server.cfg +set onesync legacy
