Reproduction

So this is kinda weird i used Proton GE for a quite some time. When the update came (for Proton GE Latest)
from Proton GE 10-34 to Proton GE 11-1 the issue occurred for the first time.
Back then i was able to switch back to GE-10-34 and everything got back to normal but today i have tested GE11 again and since then i can switch to any version without getting 3D audio/directional audio back.
