First Class Trouble uses a proximity-based voice chat via Vivox that when working – is awesome. However, there are some issues that can cause problems. If you are having audio issues, please check the below list for help.
How to Fix Audio Issues in First Class Trouble Game
1) Confirm in-game audio input and output devices are the correct devices you want to use.
2) Confirm via your Windows sound manager that those devices are working and if they are the same input and output devices. (Some of you may use soundboards/modulators etc to change those things)
3) Sync up your clock — this happens because Vivox uses a token sent back and forth between the server and players and if the token timer is off it wont register correctly.
On Windows 10:
(Windows button) Settings > Time & Language > Date & Time // Current date and time
You should see these options to turn the toggle on to sync up online.
I set the “Set time automatically” & “Set time zone automatically”
Make sure to restart the game after you apply the time change.
