In the past week I've encountered a problem where any custom ringtone in the ringtones folder (mp3 and ogg format) won't play when receiving incoming mobile calls (it plays some chime sound instead). But softwares such as whatsapp and signal do play the custom ringtone (both when configured to use default ringtone and also when told specifically to play it). Surprisingly though - I can change the ringtone to any of the builtin ringtones that came with graphene and they do work across the board (mobile, whatsapp, signal, etc).
This fault happens only in the user profile I'm using. When changing to owner or other profiles the custom ringtones work fine across all incoming call technologies (mobile, whatsapp, signal, etc).
To troubleshoot - I tried copying mp3 and ogg files directly to the ringtones folder, as well as importing them from the "phone ringtone" setting - neither helps. When I change profile to anything else - all works flawlessly.
I'm not sure if I broke something or if this is a bug.
Any advice?
Thanks.
