I just tested the film playback after recording some footage in offline mode. Everything seems to work pretty much like aces high II except for the sound. Sound seems to cut in and out, it's mostly absent except for guns. When just flying around there is no sound what-so-ever, however, when I'm in the proximity of the drones, my engine sound and everything else seems to comes back. I am using a Corsair 1500 headset and have tried every possible configuration all with the same result.
Just my observation.
