Warhawk BCUS98117 no audio aside from music in-game

Just as the title states, when in Warhawk BCUS98117 (1.5) in multiplayer the audio does not work at all. Strangely, it works in the Ground and Vehicle training sometimes and sometimes not, but has never worked in flight training or multiplayer. Have seen some mentions of this before in other posts. No other versions of the emulator have been confirmed to have sound working.

Log included.

Thank you.
