Why does my bottom speaker not work on the pixel 2 xl

[Android Central Question]

My bottom speaker for the pixel 2 xl does not work at all. I tried a left channel right channel YouTube video. I've tried Spotify. Is there some setting that I'm missing? I've had this phone for 4 months and never dropped it.

Welcome to Android Central! Does it also happen in Safe Mode? https://support.google.com/pixelphone/answer/2852139?hl=en

Also make sure the lower speaker isn't clogged by lint. If it looks clear, then is the phone still under warranty?
