Question / Help Problem with repeated audio

Well folks, I have the following problem I will give all the details how it is configured my audio here at OBS, he keeps repeating the audio, and the only solution I found was to disable the sound, which is on the main window of OBS, but the problem now I can not send the sound of the game because if I enable it starts with the audio problem repeated.

log file after a long test:
