I install X-Plane (newly) and install only sceneries and 733. Not any plugins installed. When I start replay the sound appear again. But it not always hear. When the aircraft on the earth everything is ok, but when in the sky (and I think higher then some height) it is appear. After landing I set flaps up, retract speed brake, turn off weather radar, turn off lights, transponder stby and set parking brake. Engines running, apu not started. Then start replay. I record it and attached it. I attached log file too. If I can give more information to solve this issue just write how i can help. Sorry for my english I hope I have written clear. Thanks.
