That is SDL2 thing. I got this error, when tested on emulator with unsupported soundcard. I will update SDL version in future, and maybe even get rid of it in favor of DirectX or OpenGL.
Thanks for your answer, it solved my issue, I didn't have connected speakers, I plugged speakers into the pc and now it works.
Yeah. I will report it to SDL mail list as error. Games shouldn't crash if people turned off sound.
