February 19, 200620 yr I have a loud hissing noise in my PMDG 744. Its there all the time. In a Cold/Dark cockpit. Outside the aircraft and even when I push the "Alt" keyboard key its still there. No sound Volumes seem to change it.Thanks,Andy
February 21, 200620 yr . . . . look for high-pressure airline leaks - particulary couplers.. Check the nosewheel/s for leaks. . i7 [email protected] | 32GB RAM | EVGA RTX 3080Ti | Maximus Hero VII | 512GB 860 Pro | 512GB 850 Pro | 256GB 840 Pro | 2TB 860 QVO | 1TB 870 EVO | Seagate 3TB Cloud | EVGA 1000 GQ | Win10 Pro | EK Custom water cooling.
February 21, 200620 yr Have a good look round the cokpit for reptiles would be my answer.Ok, options are, update the soundcard drivers and if using on board sound buy a good soundcard you should see a big difference.Is it only the 744 that does this?Try switching traffic off in the options window, you may have an aircraft near you??Try changing airports and see if the same happens??And now I am out of ideas!!Sorry for the first line, could'nt help it.Daniel
