Ringtone problem on Z3 Dual after Android 6 update

[BitBull]

Hello! After updating of my Sony Xperia Z3 Dual to Android 6 the ringtone vanishes, all other sounds works. Right after updating it has occurred next day, after reset of phone normally worked 7 days. Adjustment of level of ringtone doesn't reproduce a sound, as well as the choice or playing of the ringtone too.
The similar situation at me already arose after updating from version 4.4 on version 5.0.2 (http://talk.sonymobile.com/t5/Xperia-Z3/phone-not-ringing/m-p/983070#M16039). The situation has improved only after updating to version 5.1.1. I hope this time elimination of this problem won't take a lot of time!

@Quester
The problem is after using headphone jack or casting by Bluetooth
Sounds like a mute
To back it working you should use do no disturb and switching between moods active mood or no just switch
