My youngest sounded like that til about 5 weeks. He had discharge coming out of his eyes and everything. He's all good now except for the occasional soft snore.
Most likely all good, mama. I would say as long as it doesn't sound like he's struggling to breathe he's okay. Also, that bulb sucker is your best friend. Get anything out of his tiny nose that you can so it isn't settling back into his throat.

He doesn’t smell to have a cold

It can be normal or not normal. Could be amniotic fluid swallowed or could be cold
