No audio through SteelSeries Siberia 350 headset

I've recently gotten a new headset, the SteelSeries Siberia 350. For some reason, Path of Exile is the only app/game that doesn't seem to work with it - In every other app, game and just generally around the OS (Windows 10 x64) i can hear and use the headset just as any other sound output. Only in PoE - i can get no audio at all regardless of which settings i try.

Windows 10 x64, Steam version. My soundcard is an onboard Realtek chip. The headset firmware is up to date and SteelSeries Engine 3 is installed as well.

Multiple bumps in the future, It would be nice to get some kind of reaction :]

My Headset G633 logitech is not working either if using the DX11 but if i switch to DX9EX everything works.

Funny thing is that i get sounds on the Grinding gear logo video, but after that everything is silent and sound options says No sound and i cant even change it to use the motherboard sound.

I was working on this with the GGG support via email for 2 months and no solution was found besides "talk to SteelSeries".

Very odd that this is the only application on my computer that can't seem to output sound to the system device when its a USB headset.
