I have the 737-800 P3Dv4 and it has been going great then all of a sudden the internal sounds have been stopping. I think it happens when I change the acceleration height in the CDU actually. All PMDG sounds stop. I can still hear external GSX sounds like tractor engines. If I close the flight and come back to a saved file I made at the start the sounds are back but fuel level has gone to 181,000lbs. That cannot be changed or deleted and so the aircraft is unflyable.
Anybody know how to solve this?
