Laptop Falling Asleep While Listening To Music / Podcasts

A few weeks ago, my laptop started falling asleep in the middle of me listening to music, podcasts, etc. It never used to do this. I have the time set to turn off the screen after a minute, and then a minute after to fall asleep. Before this started being an issue, it would not fall asleep if an audio stream was in use, but now if I am on battery power, it will. This morning when my laptop was plugged in, I set the time to turn off the screen and fall asleep to a minute for when it is plugged in, and it wouldn't fall asleep while I was listening to music, so this seems to only be an issue when I'm running off of battery power.
