So this is how i got it to work right.
1. Install Mumble
2. Start Mumble as Administrator and set a Username when it prompts.
* You will appear in the waiting room,
3. Start Fh2 as administrator.
4. You should see an overlay if you set it in Mumble.
*You are connected and ready to go.
I DO HOPE MORE PEOPLE MAKE USE OF THIS.
VoiP is good and all, but I think this should be the official thing, because it allows more forms of comms, like SL to SL, etc, which VoiP doesn't.
If it auto started with FH2 in a later version, it wont need ANY separate installer other than FH2 and it wont need complex setup. You simply start FH2 and it starts up also.
