Fresh install - 2 problems in FS2CREW: PMDG 747-400 QUEEN OF THE SKIES II Posted March 3, 2021 11 minutes ago, byork said: 1. Some sounds will always come out of your main speakers. If you select your audio device and then press "HS" on the main panel, then most, but not all, of the FO's should should go through your headset. 2. You need to unlock it. From page 27 in the manual: NOTE: TO PREVENT PEOPLE FROM RAPIDLY TOGGLING VOICE AND BUTTON CONTROL ON AND OFF, THE SYSTEM WILL LOCK YOU FROM CHANGING THE INTERFACE METHOD. RIGHT CLICK THE LEFT LINE SELECT KEY TO UNLOCK THE INTERFACE METHOD. WOW. Always super quick answers! I am impressed! Thx Thanks for the answers. Yhe I knowq all good!
