If a newborn baby is snoring while sleeping, what do you do?

Nothing: Most newborns make a lot of interesting noises including snoring. You can change the baby's position and see if that helps. As long as baby is eating, pooping, peeing, and stays pink, odd noises are usually nothing to worry about. Anytime you are worried, tough, a visit with your doctor can be most beneficial.

Newborn Snoring: Newborns have periodic breathing, that is, frequent pauses and gaps in breathing. As long as lip / skin color stays nice and pink, indicating good airflow, no need to do anything at all. If snoring seems to be affecting quality of sleep or there are any changes in skin color, go see your child's pediatrician.
