Okay I figured I make this post for the new members of this clan to explain how to use mumble properly so that it will run with Cod4/Cod2...
Lets begin,
If you haven't already downloaded mumble... please download Mumble from this site here
http://mumble.sourceforge.net/After you have completed the installation process lets start configuring it
1. Once you open mumble you will see 2 windows layered on top of each other; for the address type in
38.105.81.66 and the port is
64738 and finally enter your username. Please
note DO NOT put your tags to avoid text-to-speech's retardedness eg. NoBS|Synflux - Nobs vertical line Synflux has entered the channel.

2. Now go to Configure > Settings. Then at the bottom left corner make sure
EXPERT CONFIG is CHECKED
3. On the left hand side scroll down to
"Overlay" click on it and
UNCHECK "Enable Overlay"
4. Now lets bind your Push-to-Talk, scroll up to "Basic Audio" and under "Transmission" click on the drop-down tab and click on
"Push-To-Talk"
5. Now... for your Push-to-Talk button, scroll down to "Shortcuts" then hover your cursor in the Push-to-talk box area and then press
whichever button you want to use for talking

And that concludes this very dumb tutorial, gg
