Audio completely gone, mouse cursor rarely available

We really need a fix for this, guys, this mouse things is completely unacceptable and beyond anything that any other modern game deals with - even star citizen, lol. "Turn off your steam overlay", please, let's look into the root issue.

I'm a biggest Bungie fan but this is actually really out there.

Also, the main thing here is that my audio is COMPLETELY gone, reinstall, restarts, nothing fixes it. What's going on here? Anything? Please?

Please advise and cheers.
