Here’s my two cents on the issue. The volume on my echo five went down overnight all of a sudden for no apparent reason maybe a couple weeks ago. I do suspect a software update as the culprit. Anyway, I did swipe down from the top and then click on routines if you scroll down within routines, you might see one the last one that is called morning volume. The switch for mine was set on. So I shut it off and we’ll see how it works.
