Baby monitor volume?

What do you all keep your baby monitor volume at during the night? I don’t have a video monitor, just sound, and it has 5 different volume levels. I usually keep it at second to lowest, but lately I’ve been waking up during the night just because my baby is a loud sleeper and not because he needs me. I’m wanting to switch it to the lowest volume tonight and see how it goes. So I was just curious what works for everyone else as far as volume is concerned?
