Can't recieve input when skype active

I’ve find some weird bug. My program work’s perfectly, but if I open skype, program stucks somewhere in function pollevent(). It’s happening only if some call (in skype) processed right now. I think it’s can be not problem of SDL, but problem of skype, because input of my headphones can’t reach my PC too. I tried replace pollevent by other SDL functions, but they have the same problem. Is it possible to fix that?

P.S. If this matter, I use SDL 2.0.9

No one really do not know how fix this?

Okay, this is problem only my system, I test on 3 another devices with 2 different OS, and all seems to be okay.
