Low audio quality when recording screen (no other source of sound)

[jongamboamerida]

Hello good samaritans,
I am trying to record some classes without success on audio.
Since I am recording the audio directly from the PC and with no other device connected like microphone or headset.
Isn't OBS supposed to capture the audio with no variations?

I am hearing the speaker with sort of a robot voice.

Any help on configuration or filters use?

Thanks in advance

Hello,
I had similar issues, fixed by changing Audio codec in recording settings , from "FFmpeg AAC" to "FFmpeg Opus"
