Audio completely disappears

After playing for 30-60 minutes my audio goes completely silent in the game. Changing audio settings does not help: I tried default, high dynamic and war tapes mixes.

I can alt+tab and the sound works for other apps. The sound gets back after closing and relaunching the game.

Windows 10 x64, Audient iD4. Tried 24bit 44.1kHz/96kHz discretization (this has a separate bug btw)
