I concur with @GTriderXC. Exactly the same behaviour! Many times I leave my phone untouched except a few calls, Telegram messages, and casual web-browsing sessions (can't avoid these, as I mentioned before this phone is my daily driver), but then 1-2 days later again the same no- SMS-sound-issue. I really hope fixes for bug #1506953 and bug #1596329 get rid of this nuisance.
