Ringtone volume setting grayed out

[Ikomz]

I have a Z3 Compact with Android 5.1.1. The problem is that I cannot change the volume of the ringtone. I don't have any other sound issues. As you can see from the screenshot, the ringtone volume setting is grayed out. Any idea of what could be wrong?

@Ikomz Settings-apps-all,tap on 3 dots and reset app preferences. Check again.

Done, didn't help.

Boot in safe mode. Does the same problem occur?

[Ikomz]

Yes, it's still grayed out.

You may need to perform a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 80% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).

Ok, I will try that. I have a Mac, but I suppose Sony Bridge will do the same thing? Thaks for your help!
