How to set default alarm ringtone in Android 6.0?

With my new Moto E3, every time I open _Clock_ application (to enable some alarm) I see a message: > Default alarm ringtone is silent [Change] When I tap on Change I'm redirected to _Sounds & notification_ section of Settings, where I can only see _Phone ringtone_ and _Default notification ringtone_. Both set (not silent). As for alarm I can only see alarm volume (not ringtone) which is also around half (50%) and thus not silent as well. When I open settings of _Clock_ application itself, I can see a cool set of nice settings, but -- again -- nothing around default (or not default) alarm ringtone. **How can I set default alarm ringtone or otherwise get rid if this a bit annoying reminder**? I've been out of "Android world" for around two years or so. Last version I've used was 4.3.5, but I can hardly recall something like default alarm ringtone. If I'm not mistaken, there was default tone for notifications and default ringtone, but alarm tone was always set per each alarm separately. BTW: Since this is a system-level notification, I assume that [using 3rd party app](https://android.stackexchange.com/a/168752/20449) won't solve this.
