Hello,
Recently I've had the issue on my phone where the alarm volume setting sets itself to zero. When I go to Settings -> Sound & Notification -> Volumes, the Alarm volume (and only the alarm volume) is set to zero. If I manually move it back to max volume, it stays that way until my alarm goes off the next morning, after which it promptly sets itself to zero again.
I've attempted to uninstall all apps I added since the problem started, but that did no fix my issue.
I have an HTC One m9 running Android 6.0
