The same problem exists with ARMA 3. in Dayz is started from version 0.63, I guess with the same sound system. In Dayz it happens always inside the houses, and FPS Lower drastically. I leave a video of what happens in ARMA 3, but it's exactly the same in Dayz. https://www.youtube.com/watch?v=I4sdT3vmMyI&t=61s . Please analyze this problem, or I will succeed the same as with ARMA 3, I can not play. :( Some time ago I communicated with the support of Bohemia for this error in Arma 3, and it seems that it is related to the headphones 7.1 and its special software (LOGITECH GAMING SOFTWARE in my case). Since without the headphones and their software disabled, the error does not appear.
