Voice Chat Commands
These commands affect the chat and voice commands.
/toggle cg_novoicechats

/toggle cg_novoicetext
Setting this to 0 will make it so the quick chat messages do not show their text messages (but you will still hear audio).
/toggle cg_teamchatsonly
Setting this to 0 will make it so that you only see chat messages from your team.
