Audio output change, bug or not

Hi,

This is a thing that im curious to know if its an actual bug, or if its some kind of technical limitation of the game.

Everytime i plug in an aux cable to have audio externally outputted to speakers or my headphones, beamng has its sound stuck on the default output. i cannot make beamng use the audio output im using.
By default, on my desktop, the sound is from the tv.
When i had my laptop it came out from the laptop speakers.
No matter the pc i tried this on, id have to restart beamng to have my audio at the right output.
Thats if i plug it in after beamng was open. if i open beamng after i plug in my aux its fine.
I have to restart beamng if i want my audio elsewhere.
Ive been doing this for quite a while now but i have never asked about it. Bug or nah?

Thanks.
