Can I unlink ringtone and notification volume on Android 6? I have installed this volume control app on my Android 6.0 phone in order to tune notification volume independently from ringtone volume. However, when I tried to do that, I got the following dialog:



Could someone tell me where the above-mentioned setting is located? I have searched through the Sound&amp;Notifications section, but didn't find anything.

Could it mean that the app doesn't support Android 6, or that it doesn't work without rooting?
After having tried out several volume control apps without success, I think I can safely conclude that unlinking ringtone and notification volume controls is indeed impossible without rooting.
