Please can I ask why it seems there is a lack of multiplayer sounds from other people with the same aircraft in Microsoft 2020 I have 2 carenado aircraft and it seems they both suffer from the same problem as other 3rd party aircraft do. The default aircraft that comes with the sim all are great except for 3rd party content, is it a problem implementing it with the developer kit at the moment or just an over sight when producing these aircraft, I hate to hear a silent plane start up next to me, kind regards Dave

There's a setting in MSFS that basically makes your cockpit nearly silent...I think it's something like headset in the sound options.  Is that on?

No I turned it to default, it simply hasn't been implemented for some reason it's not just carenado many others too, makes me wonder if they do not have full functionality of the developer stuff yet. But the default aircraft multi player sound is good
