Ringtone--only ringtone-- not working on speaker

[TM529]

I have a Samsung galaxy s7 running Android 7.0 that is having a very bizarre problem. For some unexplainable reason, my ringtone, and only my ringtone does not work out loud. At this point, I can hear all texting, email, misc. notifications out loud, as well as the locking/unlocking sounds, but when someone calls me, the sound is completely silent. When headphones are plugged in I can hear the ringtone through headphones-- but not out loud. When I restart my phone, the ringtone is audible for the first one or two times a call comes through, and then becomes inaudible again. I have checked all my volume settings (they are all on loudest), tried resetting my ringtone, and disabled the Easy Mute setting. Any other suggestions? Thanks.

Nope. Checked that several times. I also just tried resetting settings, and I heard the ringtone once, then it stopped again.....
