HDMI Capture audio isn't working as excepted

I'm using OBS to record old family movies. I got a new HDMI capture device via USB.
The OBS recognize, and I record great, but in last days, I was check the records and in the sound, I hear my self in the room, since the microphone was open.
I try to mute all audio input and keep the HDMI capture, but there was no sound. After checking I saw the sound is showed under Mic/Aux, and not under HDMI capture.
Seem that all the audio is merged in the Mic/Aux.
