Thank you zsawyer for the reply. However, I wasn't able to uncover the problem. Our Mumble Audio Output settings match what exactly is shown in the installation wiki with our minimum volumes set to 0%. The MumblePAHelper confirms that Mumble link is working and is sending positional data. We are getting positional audio on the game sounds though. We are using different speaker setups (stereo, 5.2 and 7.1 Surround). Stumped. lol Thanks again for the reply.
