I do in fact love the little sound effects, a door opening or closing, little step sounds or cars passing by on the street. That kind of things give some life and motion to the renders. I understand that they require dev time, tuning and research though. It's something that is really present in mangas that I appreciate. They have symbols for all the little sounds and are using them all the time. Something less present in western comics. (I didn't learn why the translation I read as a kid had so much big words everywhere in the panels before some time.) VNs are a special medium, you can add those sound to the story directly no need to write them down. I just feel it's a waste not to use the opportunity. And let's face it sex sounds add to the allure of a scene too. And I'm not talking about the moaning , I agree with Dessolos on that. And when it's bad it's also sadly verry noticeable like an old truck engine sound that's as strong as the music and doesn't even loop properly to represent a modern car sound.
I would prefer more sounds in VN but the work needed for that is not free either so I make due with what is offered.
Also a silent baby is verry weird depending on the age, but again in an Adult VN I understand why you would not want to give a child to much presence.
