Every time after a server restart, voice comms aren't working until there's a changelevel.
I've already ruled out the server.cfg and sourcemod plugins as I've tired starting the server without those and the issue still persists.
Any ideas what could be causing this behaviour?

You could also put the voice comms settings in autoexec.cfg which is executed prior to the first map loading.

I'll try that and I'll report back!

It totally worked, thanks!
