In the showcase "Commanding" there is a sound mix issue, once Papa bear's dialogue starts environmental sound decreases to a near muted state (this occurs at the very start of the mission), Bennett's sound volume also decreases (this occurs after the helicopter lands at the first way-point of the mission), both environmental and Bennett's sound volume seem to decrease significantly.

"Solar power" plays at a normal volume, so does Papa Bear's dialogue (after the landing), once the player reaches the second way-point(link up with foxtrot) Bennett's speech goes back to normal, but the environmental sounds are still low through the whole showcase.
