I will look further in the FMC setting, the device is still not found (the one of my OS) Thanks for your help

First thanks a lot for your fast answer. For the full names you mean the dispaly name ? Both FSX and my OS are pointing to the same device. However when I load the PMDG 777 and go in the FMS sound setting, there is no sound device available ... Do I have to program it in the aircraift.cfg file or something like that before doing it on FSX ??

Hello, I am in the same case as you Dreamflight767 I think. All the external sounds are working properly (those in the aircraft file) but not the cockpit sound, in fact all those in the FSX/sound/PMDG/777X directory. I also have the PMDG 747 and 737NGX and they both work properly. I'm not using any specific sound device. Do know how to solve this ? Thanks
