Silent ringtone sound

[GT-R]

The problem with the quiet sound of an incoming call. But
The sound of notifications and alarm clock is normal. And in the player itself, the established ringtone plays without problems.
Did:
- reset to factory settings
- start in safe mode
- software repair via Xperia Companion
New phone, updated from 6.0 to 8.0 android
Sony XZ (F8331) OS 41.3.A.2.192-R8E

Are you using a preloaded ringtone or your own ringtone? if the later, are the ringtones in the internal storage or the SD card?

[GT-R]

I use my ringtone downloaded in the phone's memory. In the player rington sounds like it should be.
I tried to cut the ringtone to 30 seconds, weight ~ 1mb
