Now I have the same problem with the robotic/metallic voice.
It happened when I switched from an Intel platform (i7 4790k, msi z97) to an AMD platform (x3700, ao elite x570). Both platforms with Win10 (1903).
I played DCS multiplayer many hours before without issues. The first time I played DCS multiplayer with my new gaming rig I have this issue with my Rift S.
