Well, the OBS has a complex audio encoder with has default settings that doesn't work in a lot of softwares, so guys here keep sayin that the Sony Vegas has a problem, Media Player has a problem, Houston has a problem, but seems that they can't figure why.
First follow these instruction
(Change OBS output audio encoder), then, double check OBS output audio device.
On OBS Main screen > Settings > Audio > Output Device for Desktop (or something like this) and chance to the one where currently is hearding your sound (Speakers / Headset etc...)
Then you're done! Good Job!
